I checked his cage and there was a small pile of poop in his hidey shelter. There wasn't a ton, but there was some. it looked pretty normalHe needs to see a rabbit savvy vet. Rabbits should poop 150-300 poops per day. I'm not sure why he would not be pooping if he is eating, are you sure he isn't pooping in an area that you don't know about? What did the last poops look like?
thanks!Before a rabbit stops pooping, he'll stop eating. If he has a blockage in his gut and is unable to poop, he'll still stop eating.
If a rabbit ever refuses any food he normally eats, then that is a sign that something is wrong. If he suddenly eats less than his usual amount, that can also mean something is wrong.
So all that to say that if your rabbit is eating his normal amount of pellets and is eating plenty of hay, then he must be pooping in areas you aren't seeing. That's not surprising if he is outside.
Not quite sure how large a "handful" may be but a general rule of thumb for hay-eating is that a rabbit should eat his body size in hay every day. Since they like to pick through the hay, they should have more than their body size available throughout the day.
For your future reference, if a rabbit ever stops eating for 12 hours, that would be considered a dire emergency and he would need immediate vet intervention. If a rabbit ever does stop pooping, that is what is called GI stasis. GI stasis usually has warning signs though -- like refusing to eat, producing smaller poos. If those signs are ignored and a rabbit completely stops pooping, he would be on death's door. Rabbits that have had all the warning signs and get to the point of not pooping at all have a tough chance of survival even with vet intervention.
Thankfully, that does not seem to be the case with your rabbit.
