I made up a batch of the cats food and I didn't notice an off smell until I added the supplements. I usually mix the supplements with water then add that to the meat, but I forgot and added the water first then threw the supplements on top and mixed it. I add taurine, b-complex, vitamin e, and lite salt. After mixing the food smelled different to me. I fed the cats and 3 out of 4 ate it. Vivi refused to eat it so I stuck her's in the fridge and tried again. I smelled it again after she refused and it really smells really weird now. Is the meat bad or is this because I didn't mix the supplements with water first?
