I've had Raegan since she was 3 1/2 weeks old (abandoned by a feral colony) and since then she has been doing very well. She's had her check-ups with the vet, and her stool has been checked for worms. I recently just switched her over from the older cats' food (after she went to hard food, she wouldn't eat anything else) to her new kitten food. She had only been on it for a week before her poop started to become runny. We've switched her back so that we can try to do it more gradually than the last time. But, it isn't hardening. She had only been on that new food for a week... Other than that, she is as energetic as ever. Outside of the litterbox, it seems like everything is fine. Should I be worried? Or should I just keep doing what I am doing?
BTW, I have also gotten some dietary vitamins to help her digest her food easier.
