To make a long story short.
I have been having parasite problems. I don't know where it started, but I ended up separating all of my leo's. But I was still feeding crickets. Last week I got fecal samples from all of my leos and brought them to the vet. All came back positive for pinworms. One came back positive for Protozoa (When I bought her, I took her to the vet for a fecal check, and she had protozoa, we treated it twice, and she still has them!!). I got medication for everyone and administered it the weekend.
I e-mailed a very reputable breeder, one I have purchased from before, and told him of my problems. He told me that is the reason he doesn't feed crickets, and he only feeds his mealies and pinkies. That is why I wanted to try pinks. I know of course too much is bad, but once a month is what I was going for. And I like my leo's fat. Also I am prepairing for breeding.
