Hi everyone! This is Briana, formerly Pongothebunny928. I changed my username 
Okay, Pongo….I don’t even know where to start. For the majority of his 2 and a half year life he has suffered from chronic poopy butt. We(my mother and I) have tried everything we can to fix or minimize this problem. Normally, he has unlimited hay & some oxbow pellets, but we concluded that the pellets were causing the problem. So, about 2 or 3 weeks ago I decided to take him off of the pellets and just feed him his hay. As far as his poopy butt goes, I haven’t seen any problems; however, about a week after changing his diet he started acting very odd.
He is litter box trained, so I have one cat litter box in his cage & also a flat pan litter box that sits under his hay ball. Since feeding him only hay, he has been consuming 2 to 3 times more water. I wasn’t surprised by this since he is eating a lot of grasses. But then he started peeing on his flat litter pan(which he used to NEVER do!). It got to a point where he was peeing all over his hay, so obviously I’ve had to clean that out on a daily basis. Since then it has gotten progressively worse. He still uses his litter box, but he is peeing large amounts on his flat litter pan all over his hay and then just sitting on it. When I let him out of his cage his little back feet are wet with pee, and if he sat on the blanket for even just a couple seconds, there would be a damp spot when he hopped away. Now, not only is he peeing on his flat litter pan and in his litter box, but also just on the floor of the cage. He’s peeing everywhere! Also, since changing his diet, I’ve noticed that his tummy has been gurgling very loudly. I understand that this is normal but if he did do it before it must have been awfully quiet.
I’m completely lost as to what I should do. My mom and I decided last night to start giving him an eighth of a cup of pellets a day and seeing how it goes, hopefully working him back up to a normal amount. As of right now his entire cage floor is covered in newspaper to help absorb anything. I can’t think of anything that would have caused this other than his diet change.
I’m in college, so it’s pretty stressful having my classes and not being able to keep up with what’s going on with my bun! Any advice as to why this is happening and any way I can fix it would be incredibly helpful! Thank you all!
