I'm vegetarian so I'm clueless on this subject and don't currently have meat or fish in the house, but I know protein is important for them and plus I work in a deli and can get meat at a discount

I saw chicken and turkey on the safe foods list, & saw that pork is okay but ham isn't good (I assume it's too salty??). Are deli meats acceptable or are they too processed? I'm sure I can get meat off the bone if deli meat is not okay. Do they prefer raw or cooked meat? I'd rather not put meat in my frying pan, but maybe I could get a separate small pan to use just for them. However, if I can buy it cooked (or feed it raw) that would be preferable.
I also have seen that people feed them shrimp, and I know I can get frozen shrimp easily. Should I cook them or just thaw and feed them raw?
There is so much to consider, lol. I am happy to do some trial and error as far as what they like but don't want to feed them anything that would be bad for them!
Thanks!
