I'm very concerned about the quality of the food I've been giving my two ferals. I have been buying 9 Lives both dry and wet because I thought it was OK but on another discussion section on ferals, it was stated that 9 Lives is bad. I'll feed them whatever they need but I must know what is the best food. Also do I just stop the 9 Lives or gradually introduce the new food? I want to do the best for these little guys.
