Mine don't really like the lamb or the venison...they love the rabbit of course it is the most expensive.
I have to take the chill out of it to get mine to eat...I spoil them.
I sometimes will put them in the microwave for 7 seconds if I'm in a hurry. If not, I put them in a ziplock bag in some warm water for about 5 min.
Then I mash it up into smaller sizes for Myah, Chloe' will scarf it down in one big gulp if I don't break it up. I also use the patties not the medallions. When feeding 2, it is more cost effective.
