Doesn't a urinary infection cause that? For an indoor cat, I strongly suspect there's a problem with canned food sometimes. When I had a cat a long while back, every so often you'd open a can of cat food and it'd have worms, or the cat would (after being extremely excited as you were opening the can), sniff and propel himself away from the food. You'd look and notice it was off (like it had something crawling in it).
