I will slightly buck the consensus here.
When feeding an animal, number of prey items can be somewhat fudged when you account for total mass consumed.
As examples: Would I feed a 700g male ball three medium rats? Never. Would I feed a 2500g female ball a dozen mice? Absolutely. Would I feed a 2.4m blackhead three large ReptiLinks, a dozen chicken hearts, and a score of smelt? Might happen once in a while now and then.
The total mass of food consumed consumed in each case is the determining factor.
Saying “3 prey items” is too loose of a criteria for us to be able to judge. If it is one small rat and two fuzzies going into a 1600+g animal, I do not see it as a problem. If it is three crawler rats going into a 300g animal, then we have an issue
