Okay guys... I have a new shipment of mice coming in on the weekend (if all goes well) and so I have started to prepare for larger numbers. I can't continue to buy aquariums and lids, so after looking at the numerous pictures on here I have decided to 'make' my own!
This is what I have so far:
This is one of the smaller containers I bought (huge sale!) and would be a male bin. I wanted to practice on the small cheap ones before trying my hand on the bigger bins.
My big question is, should I put mesh on the lid as well, or is a front opening sufficient?
