Ok I took my cats to the vets on Saturday because of them peeing on my towels and infront of the litter box. He told me they didnt feel like they had UTI's so he put them on Amoxi (whatever that is) and I was to give them 1 pill twice a day. He gave them one there and then we gave then another one that night. Well, Sunday morning I got up to take the dogs out nad there was what I think was blood on my carpet. I cleaned it all up and then when I got up again for good my sister in law said Ninnie ( my older cat) pooped right in the middle of the living room floor and then starting like drooling/foaming at the mouth. So I havent given them anymore pills. I am actually scared to. She seems fine today but how can I trust the vet? Do I take them back or just let them go and try to do stuff myself? We are tearing up the carpet around there litter box and putting tiles down tongiht. Hopefully that will help and also during the day I have that feliway plugged in right above there litter box. Hummm...some advice pleasel?
