i was at petco getting some silversides for my P's. ya i know petco = bad but they are the only place i can find certain things like frozen krill. but anyways the guy there said that if i feed my P's silverside to much that the salt in the silversides will mess up the P's liver. and i was wondering if this is true. i have never fed them silverside and was wanting to try it so how often can i feed them this if what the guy says is true. thanks for the help.
