Is this enough ventilation?

[Oompoofishy]

I was wondering if this is enough ventilation holes for a T enclosure?

I was actually thinking of cutting the top middle rectangle and replacing it with some sort of mesh? But I know many have warned against it as Ts either can chew through them or get caught and potentially hurt themselves.

In that case, what other materials can I use? TIA!!!

Thats about the ventilation i use in cages like that if not for a rainforrest soricies, then i add ventilation on the sides as well! But add a few more holes. More ventilation is usally better

Looks fine to me. If anything make the air holes a tiny bit larger.
