For the first time since we've been caring for him, our outdoor community kitty has fleas. He's been so itchy and scratchy the past week to 10 days. I was thinking it was food related since we changed food about 3-4 weeks ago, but then I saw a flea crawling on him. I got topical flea meds from the vet today and also got a tapeworm pill. I applied the flea med earlier this evening (he thought I was killing him) and he's already more comfortable. When should I give him the tapeworm meds? I will call the vet tomorrow and ask, but just in case I don't hear back from them, I thought I would ask here.
