Even with medical problems, they need to be checked. Yoshi, my pee-boy gets blood work once a year. Just to make sure his medicine isn't making him sick!

I've heard a lot of people say "Oh, I'll wait a day and see what happens" As we all know, or should know by now, cats HIDE their illness, its part of being a cat. As for waiting that extra day, with male cats that can be fatal!!

Good call Jen!
