Hi, i'm semi new to rabbits, i've had my first one (Sera, lop) for almost 2 years, and Epies for just a year. Sera turned 4 last august, and began to have potty problems. She'd drink a lot of water and then have an accident where ever she was and thump like she was mad about it. After going to the vet, he treated her for a bladder infection and all was well. Since then, she's had 2 more times (including now) where she's drinking an excess of water and peeing excessively around in her cage and not always in her litterbox, and almost always having matting of her fur on her bum and legs. The vet recently called and suggested we get blood work to see if she has kidney disease and it made me wonder... are there things i feed my bunny that could cause her to have that? And are there veggies she can eat that can help cure/prevent that. Right now all she eats is 1/8 cup of pellets, romaine lettuce, and loads and loads of hay (she loves hay).
