Good morning, my 12 week old kitten, B, has some bathroom problems. We got her and her sister at 9 weeks and noticed that she was not gaining weight and her stools were loose/liquid. She had two tests for worms but both were negative. Vet put her on dewormer, sulfadimethoxine and pyrantel, along with a vitamin supplement. She has been on them for almost 7 days, I have seen an improvement in her stools, but she still has diarrhea. It could be mixed with hard stool or just a small amount on its own. This morning there was a small amount of mucus in it, but she wasn't able to make it to the little box in time. After I saw that I placed her into the litter box and she had a hard stool right after. The vet recommend Royal Canin baby cat for her. I know that it isn't grain free but I'm trying to help her. It has been 16 years since I've had to deal with a kitten, any info would be helpful. Thank you!
