I have an 18-year-old spayed female, in pretty good shape except for a couple of things. She as bad breath, which could be caused by a bad tooth, etc., and she sometimes wails after moving her bowels. I'm thinking I could put some sort of oil in her food for the latter, but I want to take her for a complete checkup. I can't hold her mouth open to see what's going on. The question is that a few years ago, I was going to put her in a kennel for a couple of days, but they wouldn't take her without proof of shots. She was my son's cat, and he did get them all, but I don't have the proof. She has been indoors for years, so I really don't worry about it. I was going to go to the docs at PetSmart, but I'm afraid they'll want me to duplicate the shots, which I really can't afford right now. Has anyone else had this happen? Thanks in advance.
