I would personally chose more dense net. The size of squares are just right for him to tangle his pawn in the net if he'll do some funny business.

I didn't think to check the density of the net when I bought it. 🤦 You're right. I don't want to leave him near the net unattended anyway, and now I'm going to make sure his paw doesn't get stuck. Thank you for the warning.
