My cats paw might be broken but I don’t know what the cost would be for them to check him out. Is there a fee to get him checked out on top of the procedure they might have to do

There's always an office fee unless you are getting booster vaccines that are considered tech visits.

Yes, there's a small fee... but it may be worth a piece of mind. They will be up front and honest about anything your cat may need.

$45 office visit, on top of any procedure

I would think so. Call them
