Considring Offering Mice

Just in case you guys were tired of my stupid questions, I came up with a few more...

I have a very picky cat who is an awful eater, but seemed to really relish the mouse he caught a few weeks ago, and since then I have been considering offering him mice. So...

Are the mice produced for feeding to pet reptiles safe to feed my cat?

If so, how does one defrost such a thing, and is it really necessary to cut it open as I don't know if I could do that...?

Based on what I've read (cause I haven't tried feeding Ritz a mouse, yet):
Yes absolutely the mice fed to reptiles is purfectly safe to feed to cats.
And regarding whether to cut/defrost: cut--depends on the size and cat. Personally I'd start with small mice (pinkies) and build up from there.
Mice in the wild are more or less room temperature, so I would simply put a frozen mouse in the refrigerator the day before you plan on feeding to allow sufficient time for the mouse to defrost. (With perhaps a sign on it saying to the effect: "this is not a chocolate covered mouse, do not eat", for anyone in your family/visitors who might want a midnight snack.)

Yes those mice bred for pet reptiles are safe, I do however ensure my supply comes from those that follow strict ethical standards regarding their life style, food and dispatch. Mine love mice but they are more expensive than Day old chicks ( Docs), which regarding ethics probably would be the go to whole food of choice as they are a natural by product of the chicken/ egg industry ie all the boy chicks. I do however have one cat in particular who loves small mice in preference. Cost in the Uk= £3.50 for 50 Docs , £12.00 for 50 small mice. I would find a local shop to start with where you can buy a few and see if your cat enjoys them otherwise you have paid out for delivery and quite some freezer space for the Docs.
I take my mice and docs out of the freezer the night before and place in the fridge overnight. As mentioned above some like warmer prey so either dip in some warm water to get up to body temperature or place in a plastic bag first and dip in warm water to keep the fur dry. If this is new to them they may look at the mice/ docs as a furry toy hence the need to cut open to start with. This I find is better done when partially frozen then the uggghhh factor is less especially with Docs as the yolk sac is still frozen.

the only thing is not to feed too cold a meal (the Rogue will eat with gusto but vomit shortly after), and not to rely on too many baby animals (need adults or at least weaned juveniles to get decent nutrition and probiotics).

Definitely shop around, prices vary, as do shipping costs. If he already relished an adult mouse, perfect! Go with those. You'll want to cut in half at first until he gets the drift. I had to start with pinkies, work my way up the age ladder until now I don't have to cut jumbo mice at all (do still have to cut small rats, though).

Unfortunately my guys don't like cavies much, or rabbits, but if you can do try to add as much variety as possible.

I don't know if I could cut a mouse in half. I have faith that Dusty Springfield will eat it if Squeek won't. I'm not worried about it being nutritionally complete because it would only be supplemental. Thanks for the tips about defrosting - that really helps! I'm still trying to make up my mind whether or not to do it, though!

My youngest, Monster, loves pinkie mice! The pinkies thaw very quickly. I just take one out of the freezer and put it in a zip lock bag on the counter. It'll thaw in about 30 mins. My older 5 won't touch them, so Monster got to eat all 6 the other day when I tried to give one to everyone. I've never had to cut one in half, but I don't think I could. I haven't tried bigger mice with Monster because I just use them for a snack.
