Mattie gets them twice a day after she takes her antibiotics. My SO is very liberal with treats which is not good because Mattie is no small cat.
Chloe gets them about 1x a day.
I buy all sorts of treats....right now I have some freeze-dried pieces of chicken and salmon, Meow Mix moist treats, and Temptations Hairball treats (for Mattie, which I buy even though they have petroleom in them). I have some Salmon Purrz somewhere but I won't buy those again.
I also buy the Feline Greenies and the Nutro Max treats sometimes or I just give them pieces of their regular dry food as a treat.
