My husband brought home a large bottle of the Party Mix (we've tried different flavors, Ocean Side is the most popular) and all three cats, ranging in age from 8 months to 10 years went nuts!
They know when "treat time" is supposed to be (yes, my cats can tell time, I've never had one that couldn't) and they go and sit in front of the cabinet where the treats are kept. If one of us isn't there pronto, one of them comes and gets us! They aren't fooling around when it comes to their treats.
Hubbie tried to sneak a different kind to them and they literally turned up their noses (in tantum) and walked away. Wouldn't touch them. Spoiled little buggers, but we love them and they love their Ocean Side, what are you going to do?
