The way my cat breathes worries me. It’s been months. the breathing sounds noisy as if it’s through a straw. sometimes grunting if I hold him. He sleeps way more now. He’s 5 years old and probably around 17 pounds so a bit over weight. I changed his food from meox mix to a healthy dry food and chicken primavera fancy feast cans. I’m not sure what to do. I’ve been to the vet. They ruled out the x rays, they tried giving him something for Upper respiratory symptoms it didn’t do nothing. Not sure what to do. He also is very twitchy with his back scratches his ear, grooms a lot. And I’m not sure what that is because he’s over his fleas now already.
