One of our kittens has has very bad diarreah to the point there was blood one time. Now its just extremely soft and not formed at all. She gets it all on her feet, legs, tail (to to bath her twice) then it ends up all over the house on carpets, sofas, kids toys etc which obviously poses health risks if i dont happen to see where she goes every single time. Vet doesnt seem concerned but its getting very frustrating having to clean poo off everything. Her food was gradually changed over and shes been on it over a week now and still not any better. Is there anything i can give her to sort it out??
