My cat has been on wet food for about 2 weeks now, he loves it but I have noticed he has been more gassy, he is scooting across the carpet after using the litter, he's been licking alot as well and I have noticed some small poops around the house, it's like they just fall from his bum. This all started about a few days ago, and he is on grain free wet food. He is still going to the litter regularly though and is still very playful. Any suggestions?
