I feed my little one (Tashi) Evo Small Bites, the chicken formula . I rescued her about 6 months ago .. I've seen a tremendous improvement in her skin and coat since I've had her . When I got her she weighed was 18 months old and weighed 3.5 lbs, I have her up to 5 lbs now and shes healthy and good at this weight
I fed my cats Evo too , before I let my ex boyfriend have them when we parted . An 8lb bag of the Evo lasts for about a month

I love it .
I'll be watching this thread , though , to see if anyone has any suggestions they think are better than Evo .
