I have a similar problem, not cost wise but size wise. I only have three snakes but keeping rats with my veggies is not appealing. I could use a freezer that is 2 Cu Ft just so it does not take up a lot of room and I can keep the rats separate. Looks like I'm just not gonna find what I would like.
Why not? Its just raw meat, like a steak or porkchop. If you're worried about contamination, just put the feeders inside an airtight tupperware. If it's a sight thing, line the container with paper or find an opaque one.
