Well, it sounds like you are on the right track. Does that website happen to say what you treat roundworms/hookworms with? It's gross I know, but to save the cost of another vet visit, you could take a "sample" of what came out of MBK to the vet tomorrow and confirm that it's one of those worms. If the treatment is Flagyl, then you are on the right track already! Sometimes they will pass the worms as the meds are killing them (worms, not the cat). It sounds like he has all the symptoms. Hopefully he'll get back to 100% after the worms are out of his little body! I'm sure C is fine- just watch her box carefully for the next several days. Also, I am assuming you are certain it did come from MBK? I guess time will tell on that one! Keep us posted.
