So far I've tried with my girls: chicken, turkey, ground beef and shrimps.
The first time I offered shrimp it was a very funny show! I had Kiwi and Stella out for playtime in the hallway and sat down with a small dish of cut up shrimp peices. Both went for the shrimp very quickly and proceeded to annoint with them! My big Kiwi girl did so quite a few times and was pink on half her body from head to toe with frothy shrimp spit! Stella annointed once or twice and then went to town eating. Kiwi would annoint/eat, annoint/eat, and so over and over again.
Faith also enjoyed hers but was much more a lady with her little ****tail
So far the shrimp seemed to be the most liked followed by the chicken. All meats have been eaten fairly quickly, sometimes not necessarily when I have them out to play or cuddle but if I put some in their food dish it is always gone in the morning.
I personally find the shrimp easiest to give as treats. I have a pretty big bag of small cooked northern shrimp in the freezer and it takes very little time to thaw out a few for the girls.
So far, none of my girls have taken a liking to any type of fruit or veggie though...
