I have a liter of 5 feral kitties, 6-8 weeks old had them vetted on sat, shots wormed and frontlined, they had all been doing well, but today one of the little girls is "not herself" she had been the playful one, today seems lethargic and sleeps alot. I don't know if she is having a reaction to the medication or is truly sick, I don't have the money to take her to a vet, the CAHS helped us on Sat and only charged 35 dollars, I was just wondering if anyone had any suggestions/ideas?
