Yes, every one seemed surprized that an adult had worm, BUT he was a stray and when I first brought him in he had worm. I guess it was just that the worming medicine did not work 100%. And Lucas is on a new food now, so I will keep him in a separate room again today to determine if it is helping. He is so sad in "lock up" but I have too many cats and litter boxes to know for sure any other way.
It is so ironic that you said Pepper had a bad upper respiratory and now he is a rather large cat. My Amber had a severe case after I got her and she almost died, and now she is a bit on the large size. (she's big for her size, she has a very small head so I assume a very small bone structure) But she can be big, at least she's alive.
