My cat has had a pretty big appetite lately. I'm feeding her canned food mostly but very good pet food including salmon and tuna. I'm concerned she may have tapeworms since she's been eating about 6 tablespoons of food a day, maybe 7. I was so concerned that I bought one of the over the counter worm pills and gave it to her which didn't seem to do anything. I have not felt any fleas on her but do see her scratching now and then. She always goes to the bathroom outside so I can't check her stools ,but I've not seen any worms in her butt. My other cat is very big and eating half of the food she is but I think he's also getting food elsewhere in the neighborhood since he is quite a charmer.
