@AidaB , I had a look around. Cage creations don't do the perspex grids. The ones on Amazon seem to all be rectangular but I only had a quick glance. There may well be some standard size ones. Etsy will sell some custom sized and there is probably a way of making the odd sized ones fit by cutting down a normal grid for the space left over. I think we are all quite inventive with our piggy cages!
