I am just now in the midst of transitioning Cosmo from NV Instinct to TOTW Pacific Stream only. My vet highly suggested we switch from the NV Instinct because it was really too high in protein for Cosmo (he was drinking tons and tons of water).
So now I give him TOTW and he is loving it and since I'm slowly transitioning him the poos are not running. Right now I'm 50/50 for a few days then I'll go 75/25 for a few days and then by the weekend I should be feeding him 100% TOTW. I know it's rated high on all food charts and only drawback I have seen as well is that it's made in a Diamond Plant with all the recalls, but there have been a lot of great foods recalled so you just never know. Look at the NV and Natural Balance had a recall if I'm not mistaken a while back.
