True! There’s always rats on CL here. Although they’re live which I think is dangerous to them no? So you’d have to kill them yourself which might not be for everyone. I don’t think I’ve seen frozen ones on there yet.
You could ask. I feed my ball pythons live, but have frozen mice for my male hoggie and a special needs ball python (although she has finally managed to strike, wrap, and eat several rat pinkies after 2 yrs of assist feeding). I prekill the mice i feed my female hoggies. I get them all from the same guy. Delivers to my door every Tuesday.
