I've seen those! I like them, but for more active snakes I'm not sure of the security.

Luckily Kenyans seem to thrive in small cages. I think you are good to go for a male. There could be a possibility of nose rub on that side screen. The fix is to use a plastic (acrylic for example) panel velcro'd to the inside frame of that screen if it happens.
