I’ve noticed very small markings on the towel in my rabbit’s exercise pen. I took him to the vet three weeks ago, because I was concerned about a urinary tract infection or stones. The vet checked his bladder and felt around for stones and said everything seemed normal, but she put him on an antibiotic for precautionary reasons. He was on the antibiotic (Baytril) for two weeks, and everything seemed to be getting better. His pee is yellow, no signs of blood, and he is pooping the regular amount. He eats all of his vegetables (cilantro and romaine lettuce) on a daily basis and is very active; showing no signs of lethargy. I give him very few pellets and a lot of hay. Today I went to clean his litter box, and I noticed small spots of pee again on his towel. Is it possible that he’s stepping in his pee in his litter box and tracking it on his paws? I try to clean his litter box at least once every other day. I use carefresh litter, so it is pretty absorptive. I’m very concerned about this! I’m not sure how old he is… I adopted him a couple of months ago and they said between 2-3 years because of his activity level…. but that’s not certain. Thoughts????
