are feline greenies recommended? my cat had diarhea last night and i'm wondering if it's from the greenies. i didn't give them to him today. i can't find much info on them when i search. 6-8 twice a day seems like a lot of treats for a cat. i usually give my cat two frisky treats in the morning and two or three after i play with him, groom him, clip his nails, or anything else that deserves a reward.
