Wanted to update this, for those that are interested!
I've gotten two of my cats to eat mice now. They love them, and I've noticed (even with only occasional feeding, as my production isn't stable enough to completely switch them over yet) a significant increase in energy, especially for my three legged girl, Paperclip. I'm not sure on her age, but I've had her for going on 6 years now (already an adult when I found her). She ate a few 6 day old mice last night, and was running and playing through the apartment! It's pretty rare to see her actually play with the other cats. Loved seeing the boost of energy. Boots, who is around 6 years old, loves her mice as well, and is considerably more energetic after eating them.
My production is finally starting to ramp up. In the last two days, I've had 4 litters born, and around 44 pinkies all together. That's not counting the older litters I have growing up to breed. I have a bunch of pregnant does that should have their litters in the next 1 to 2 weeks. I'm breeding for feeders, as well as pet/show quality mice (I got a bit hooked...). My feeder lines aren't fully established yet, so the cats are getting culls from my pet/show lines at the moment. I find it a bit easier to feed them mice that are about a week old, instead of adults. They don't toss them around as much, and I have to cut open adults to get them eating. Plus it takes quite a bit longer for them to eat adults, than a few week-old babies.
Still no luck getting my other cat, Lightbulb, to touch the mice. Will probably have to cut some pinkies up and mix them with wet food to get him started.
