I’ve seen people try to ‘assist feed’ down the wrong tube. They didn’t realize that it was then considered force feeding… and was causing more stress by trying to push a food item in the glottis.
The last time I saw this happen was a pet shop manager was shown how to by a vet… And instead of doing it themselves, wrongly explained to the employee how to do it.
It’s honestly something I think should be shown to an owner by a knowledgeable keeper (if not veterinary staff) regardless. Not something that we simply send a video or two to someone online.
Many reptile keepers are too gung ho about doing it themselves and I hope that changes soon as more keepers go into veterinary fields
