Mudpuppy
Junior Guinea Pig
My Muppet (approx. 3) seems to be eating/drinking/ pooping/moving around etc as normal, but I've noticed a very slight change - he's ever so slightly narked and seems slightly moodier than usual. Also, when I pet him, he seems to squeak slightly more high pitched than normal and I'm not comfortable with it - I'm sure it's not his usual contented squeak. I have given him a dose of ivermectin in case he has mites/fleas (as he doesn't seem to enjoy being touched as he previously did), but before I take him to the vet, does anyone have any ideas what might be the problem? I wonder if he has a bit of a UTI seeing as he seems to be squeaking when I pet down his back/sides? 
Thank you

Thank you
