To make the story short, my cat appears to have chewed and swallowed a portion of his toy. The toy was a sewn cylinder of faux fur with a plastic bit on one end and loop at the end for attaching to a string. In itself, it was too big for a cat to swallow, but I observed Mr. Kitty chewing on it and grew suspicious. When I grabbed it, there was about an inch or so of the fur left on the end with the plastic bit, which I took away and bagged in case we needed to show the vet what he ate.
I immediately opened his mouth and looked inside, but whatever bits he had pulled off were already down the hatch. On the plus side, he appears to have broken it up and then eaten it, as opposed to eating the whole thing in one piece, and he did not eat the hard plastic or elastic loop. I'm still worried that he'll get an intestinal block though.
My dad is going to take the piece of toy to the vet and ask for formal advice tomorrow, but until then, is there anything I can do to help prevent Mr. Kitty from getting sick? We know to be looking out for vomiting, lethargy, and other symptoms that something isn't right.
Also, pending vet advice, is it best to wait for a few days and see if he's okay, or bring him to the vet immediately? I'm reluctant to take him in when it isn't necessary because he gets INCREDIBLY upset when put in the cat carrier, and he has broken claws in the past trying to get out.
Finally, how do you recognize lethargy from normal cat laziness? He's usually a sleepy, chilled out kind of cat when he isn't playing.
