These grids are VERY very sturdy. They hold themselves up nicely and look very professional. The white makes it look nice.
It would be nice if the coating was a bit thicker maybe or firmer... but that is a VERY minor comment... maybe that could be offered as a "luxury grid" option in the future (heh). That being said, my piggies don't chew at the bars too terribly much.
I LOVE the spacing!!!!! Sooooo many grids are WAY too small! :( These grids offer excellent amazing ventilation!! SO key in piggy health and happiness!!
Also, I had babies and yep, they can squeeze through. LOL But this is mentioned in the description which I think is fantastic of the store owners to have mentioned! And yep, just using some extra coroplast or doubling up grids til they grow worked great! ;) And yes... they do grow too fast so you won't need to baby proof for long. :( Ahh, at least piggies are cute even once grown up! ;)
