Ball Python escape, could he have gotten out of the house?

[Argentum]

If I had gone for that method, I personally would have used something like this:


because I would have probably kept/given them away as pets. In the UK it's not legal to feed live to snakes (at least that's what I was told) and I'd feel a bit wrong for buying rodents that were meant to be sold as pets and letting my snake kill them lolol - maybe that's inconsistent of me

That's not a bad carrier theoretically, but if the situation ever arises, it's not something I would recommend. You would be surprised just how fast a mouse can chew through those slats, or depending on how far apart they are, just squeeze out between them. When I mentioned 1/4", that's the square dimension of the opening - mice can fit through spaces that appear too small for their bones. However, it's even more likely for them to chew through the slats and have plenty of room to get out. That's why I suggested wire, they can't chew through metal unless it's a thread fine enough to bite through. I prefer 1/4" hardware cloth for keeping mice confined. Anything its head can fit through, the body can also fit through.

Incidentally, mice actually make very nice pets. Rats are even better, more intelligent, social and interactive than mice. Unfortunately, they don't have much longevity even in captivity.
