looks the part Grinling but i would be a bit concerned about the 20 gauge wire. 0.8mm thick , a fox or badger would eat through with ease.

Yes, it looks as though it's covered with "chicken wire".  Which keeps chickens in but not foxes out.

It looks good.  You would have to reinforce the bottom foot or so of the wire as mentioned before with proper weldmesh or even metal sheeting if it is to stay in one place.  Good price though.

but also useful for fruit cage.
