My

is fresh beaver meat ! For several reasons
#1- cats that are not starving want fresh meat where in the deep freeze they are hungrier and will eat anything
#2- fresh meat has eye appeal where rotten is dark
#3- using tainted meat attracts skunks,possums and critters I'm not targeting when I set cat traps that's what I want
All my cats have been caught on fresh bait not saying you won't get any on tainted but I have better success with fresh
