I just spoke with the vet. He held down some food and water and they gave him some laxative/lubricant. They x-rayed again and the mass is moving. Once it moves far enough, they're giving him an enema.
Thank you for all the great advice. My wife and I are picking up some professional quality clippers and assorted cat stuff.
After calling around, every place that grooms cats sedate them. I really don't want to knock him out once a month so we'll trim him ourselves. He should be alright if the clippers aren't too loud.
Thank God for the good news!!! They do make the furminator for cats (it’s smaller than the dogs).
It works wonders for my Mimi. No more “rolling dust balls” of fur around the house.
Did they do a blood panel?
