We've had our kitty for 6 years. In that time we've tried all kinds of cat food: dry, canned, inexpensive and pricey. Finally we found a food (Freshpet) that our cat is NUTS over!! Every time he hears the refrigerator door open, he comes running! This may make me sound a little crazy, but it has actually improved his mood. Kitty would usually come into my bedroom after his breakfast and camp out on the end of the bed, just out of arms reach, until dinner time. Well not these last few days since he has been eating Freshpet!! He comes up and wants to be petted and purrs up a storm. It's like he is thanking me for the delicious meal. He also is more active and playful in the daytime. Freshpet is a great product for kitty! We would rate it an enthusiastic 4 paws and a tail (5?)!!!
