Corn snake lost 100g in a month - advice needed

Just to start - this isn’t a post asking “do I need to go to the vet". This is a post asking “how soon do I need to go to the vet" - because it’s the night before I go on a 3 week vacation out of state and I’m kind of freaking out because I didn’t expect this.

TLDR: my elderly, disabled corn snake has lost over 100 grams in one month, going from 469 on may 20th to 361 today. He hasn’t been eating for a little under 2 months, but I didn’t expect such a massive decrease in his weight as he’s always hovered around 450 at his vet appointments to my knowledge. Unfortunately I will be away from my home for 3 weeks, so I’m not able to go to a vet appointment myself, and I’d only be able to convince my mom to go by herself (maybe keep me on speaker?) if it was an emergency, if even that. Do you think 3 weeks is too long to wait for an appointment, or is he still probably healthy enough that I can wait until I get back? (Of course I’d schedule the appointment for right as I get back)

Full context: I have this sweet old boy- er, well, he’s actually a girl, but I was incorrectly told he was a boy originally before finding out the truth years later and old habits die hard. Happy pride month and all of that. But joking aside, he has been obviously on a downward trend for years. Every late spring / early summer he stops eating for a while and will only start eating again when he sheds, lays his eggs (attempted parthenogenesis) or otherwise gets rid of them, and then sheds again. He has been scaring me for years, before I knew he was a girl I was just terrified I was losing him every year. And frankly, even once I found out by finding a mysterious clutch of eggs in “his" cage one night, I remained worried every summer after.

In 2024 I was moving across the country during his typical anorexic period prior to laying eggs, so I took him to the vet to ensure he wasn’t having any problems, especially because I hadn’t the first year he laid eggs (which was 2023). Lo and behold he had a really awful infection in his back for reasons I still don’t know - I treated him before moving, and he made the trip no problem and made a recovery, with one awful caveat - he visibly has issues with spine fusion due to arthritis caused by the infection, which makes it harder for him to move than it was before. But he still gets around, is able to drink, poop, thermoregulate, etc. Struggles with shedding but did before then too. And sometimes forgets to take care of himself but again, he did that before too. He’s also obviously lost a lot of muscle mass (although that started in like 2021) and is generally not very good at being mobile, but he manages.

In 2025 he laid eggs again (in 2024 he had some but they got reabsorbed according to X-rays) and I took him to the vet after and the vet gave him the all clear, but afterwards prescribed a painkiller which we didn’t discuss in the appointment, so I declined to have it filled. I personally have chronic pain and he absolutely cannot do oral medication, and personally I’d rather just deal with the pain than get a shot most days, so i figured for now it’d be best to just let him live out his days how he wants. But my old vet back in California did say he’d likely need to be on painkillers for the rest of his life, but the vet here initially disagreed, so I’m not sure…hence why I wanted to talk to the vet about it if the vet actually recommends it. In any event, he got all his eggs out and was otherwise doing fine.

5 months ago he went from eating two hoppers every meal (small prey for his size but he stopped eating bigger ones) to eating one hopper every meal, but he was still eating so I wasn’t worried. 2 months ago he stopped completely - but again, that isn’t too unusual for this time of year. Like I said in the tldr his weight a month ago wasn’t concerning to me - which is why this drop really is. Unless he’s hidden his eggs from me shockingly thoroughly (and laid them early), that just makes me all the more worried for him.

Originally I was going to make a much less frantic post asking about something else unusual. A little less than a week ago he shed - or more accurately I had to help him once he got started. We do the usual soak and rub routine, we’ve done it before. I hadn’t checked on him closely (ie handling) since then (I was hoping he’d eat…) and then I checked him tonight before attempting (and failing) to feed him. And the poor thing was all scraped up! A couple of small scabs / scrapes and a bunch of scales that look like they’re flaking off. I might have just dismissed it as being close to shed if I didn’t, you know, just help him shed less than a week ago. I did semi recently change his cage and move some things around, and I know with his navigational issues he ends up rubbing his back against some weird places - could that have caused the damage? It’s pretty extensive honestly…and didn’t happen until after he shed, so I’m wondering if he was just tender after I helped him? Is there something I can do in the future to help prevent that from happening? It looks painful :frowning: I just feel so bad for him. His new favorite hide is rougher in texture in some places than his old one so I’m wondering if that’s it? Rough ceramic in an aluminum dish vs an aluminum dish with a plastic lid (the old hide was too beat up and the new dish’s lid would’ve been way too noisy oml). I don’t mind baby proofing his enclosure but I want to know if there’s something else going on.

I have been low-key expecting his death since 2021 or 2022 (I can’t even remember now) and that won’t stop it from hurting terribly, but I just want him to be as comfortable as possible for the rest of his life. And selfishly? I really don’t want him to pass while I’m gone. I don’t know how old he is because I adopted him as an adult, but I’ve had him for almost 10 years and the vets think he’s pretty old. He helped me recover from the trauma of losing my first snake prematurely (pet store snake, don’t know what was wrong with her despite testing, went out due to anorexia and weight loss as well…) and he’s just done so much for me. I have 3 other snakes and i love them all dearly, but Phantom, the snake this post is about, is just…special. I just want to do right by him. If I wasn’t leaving Literally In 12 Hours I would consider rushing him to an emergency vet (I don’t exactly know of any emergency reptile vets nearby, but I’d do my best) before my trip, but that’s just not an option… but I will do whatever I can to do right by him.

Any advice is greatly appreciated. Thank you very much for reading! And I am so sorry if I broke any rules posting this, I couldn’t find the rules on mobile very easily and I was kinda writing this in a quick panic… please let me know if I did and I’ll edit things asap!

Here’s some photos of the injuries(?) I was talking about btw, I’m not as worried about this as the weight obviously, but I took these photos before I knew the weight and figured it’d be worth showing them…

And a semi recent photo of him being cute for good measure

Are you sure she hasn’t laid a clutch of slugs somewhere? Because that’s somewhere near what I’d expect for weight loss from a clutch of slugs.

@deanaii Dean has a great point. I would loook for the slugs first……

Thank you. SO MUCH. for suggesting I double check. I did do a visual inspection before but somehow the little bugger managed to hide them in his humid hide even though I thought I checked in there, since that’s where I got him from yesterday. I felt so much better when I saw the first little dried out egg :sob: I’ve been through this rodeo before so as long as he eats in the next few weeks I am far less stressed. That doesn’t get me back the hours I lost overnight to anxiety but hey, I’m not the one driving so sleep deprivation won’t kill me LOL. Thank you so much again!!

Edit: this also explains the scraping and increased activity he’s had lately (or more accurately, his increased activity explains the scraping, which I had already considered but I didn’t know why he was so restless) so it’s just a big sigh of relief all around for me.

You’re welcome. I’m glad that was the cause! I try to feed sparingly between late winter and late spring to prevent ovulation. It’s extremely successful. They are maintained at slender weights anyway.

You are a genius Dean!!! :clap::clap::clap::clap:

Hahaha. I dunno about all that. There aren’t many ways a corn can lose that much weight that quickly that don’t involve cutting tools! :grimacing:

Glad that the weight loss problem was solved. When you get back home, it might still be worth a call to the vet to get more clarity about the snake’s potential need for painkillers. If it’s in constant pain and that can be helped, it’s worth a shot. I do understand not wanting to do injections. I’m not sure I understand why it can’t get oral painkillers. Depending upon dosage, size, etc. , you might be able to put the medication inside a meal. If the snake isn’t eating, it might be a fairly simple matter to put something like a small fuzzy or a piece of ReptiLink in its mouth (meds inside the food). Often the snake will go ahead and accept the meal and swallow on its own once you get it started. The biggest catch with this is dosage frequency. It works with small meals/snacks if the snake only needs the meds every few days.

Oh my goodness I was reading and just holding my breath for your poor guy (girl). Then Dean solved it all in one guess. Well done, @deanaii I hope you can have a peaceful 3-wk vacation, even if you do need to get him to the vet when you get back.

Yeah, it was such an extreme amount of weight lost that if it was due to a parasite or naturally wasting away, I was worried i would come home to my poor snake as nothing but skin and bones. I’m so relieved it was his normal problem instead of something worse!

In your experience does this tend to happen more with older snakes than younger snakes? He didn’t start doing it until he was older, he ate like a champ when I first got him, like my younger girl who I affectionately call a garbage disposal. Then started fasting at weird times…then eggs appeared lol. I heard it happens more when they’re older but I don’t know how common this really is?

Thanks for all your help!

Yeah, my policy with Phantom is to take him to the vet after he lays eggs / after August if he hasn’t laid yet, just to make sure he doesn’t have any still stuck in him. Also just best practice with an elderly snake.

As for injections vs oral medication, it’s a Phantom specific issue. He absolutely despises oral medication - the stress he goes through with oral medication is far higher than with injections. He’s as good with the injections as a somewhat well behaved toddler - he doesn’t like it but you can do it. But I cannot open his mouth without drawing blood from his gums. He moves the card I try to open his mouth with to his gums and just walls me, and I try to keep them on his teeth but he keeps his mouth shut tight.

This happened after to the first time I gave him medicine, he visibly despised it and slowly got better and better at blocking me from giving him his meds / opening his mouth and I only barely was able to finish his treatment. I maybe didn’t put the syringe down far enough, but even the vet said he hated it when she was trying it, and he was visibly spitting out some of the medicine at the vets. But I’ve tried to open his mouth since to check for RI symptoms (mostly proactively) and every time I leave less successful than the last. It’s definitely a situation of “you’re teaching him to fight you by giving up" like with a defensive snake, but I just don’t know what else to do, and the injections really aren’t bad with him.

Unfortunately phantom is a pretty bad / inconsistent eater, but honestly? For something like pain meds you might be totally right. If I can figure out how to inject it into the prey item he can just eat it if he eats it, and if not he doesn’t get the meds. It’s just painkillers so it won’t mess up treating something directly life threatening like an infection. Being overweight isn’t that much of an issue to me (because he loves to go on hunger strikes…although I’d love if he DIDN’T do that so may need to feed less frequently for that reason lol) and even if he takes it sometimes and gets relief easily that’s a win to me. The bad part is that I probably can’t / shouldn’t give any rejected medicine prey to my garbage disposal, which is what I usually do with rejected meals… oh well though. Very small price to pay if it keeps him comfortable.

I do think the meds are once every two days though, or daily, so… it may not work long term. Overall I definitely agree, at the very least he needs to go to the vet, and I’ll definitely explicitly bring up the topic of pain medication because I do want Phantom to be happy and healthy. I should’ve asked outright during the appointment last time so yeah, definitely on the agenda this time.

Thanks very much for the advice!

Thank you for the well wishes! Yeah, the relief I felt Friday morning finding those eggs was undescribable lol. I’ve had a hell of a busy past couple days (although the non airplane day was incredibly fun) but yeah. Doing his annual checkup is first thing on my list when I get home!

Not particularly in my experience, but I’ve read that this is often the case. It seems that if they are virgins, during their younger years they don’t lay. As they age, they sometimes start. Parthenogenesis, where some eggs are actually fertile, is linked to advanced maternal age.

I have had and do have older animals. I don’t have any females who are still virgins by old age, though. Mine are bred lightly but they are normally bred at some point. My current oldest are Sceptre (18) and Dazzler (17) both females. Sceptre has laid a clutch of slugs the last year, in fact. Worried me because she’d had some egg troubles a few years ago and prolapsed. Guess we’ll see what happens this year.

That is terrifying, @caryl. I guess you can never relax fully with females! Is it just corns or do other species of snakes struggle with this same thing?

You’re right, you can never totally relax and assume an intact female absolutely won’t lay. Unfortunately it’s a thing across species. Here are a few confirmed examples. It’s also known to occur with lizards.

My female Hoggie lays clutches of slugs yearly starting in 2024, she’s never been bred and she’s 5ish years old.

My passed on Female Brooski King would double clutch slugs sometimes after laying healthy clutches. I believe it was a clutch of slugs that became egg bound that I never caught that may have caused her to pass. It’s definitely something I worry about with my colubrids.

So, so sad. Thanks for all the info and links.
