I have a rabbit, Bunny, who has been producing what I believe are excessive cecotropes. I occasionally find small clusters of them deposited randomly around her living quarters but what is more concerning is that there is a large, brown, contiguous, dried and crusted-over area in her igloo where she sleeps (photo attached for reference, warnings and apologies in advance for posting a photo of poo). This has been going on for a while and I read that the cause is typically an overly rich diet. She has always had unlimited access to Timothy hay but we used to also give her the rabbit-safe byproducts of vegetables we prepare for ourselves, ie cilantro stems, carrot tops, bok choy bottoms, cauliflower leaves, etc. We stopped giving her these a month or so ago and her diet has been strictly Timothy hay since, but she is still having this cecoptrope (or could it be diarrhea?) problem. What could be causing this? Is it time to visit the vet? Bunny is a 5 to 7 year old (we aren't sure because she was a rescue), approximately 11 lb female, Rex-looking rabbit. Thanks for your advice!
