My birdies love to play at the bottom of their cage — hopping around, chasing their toys and so on. I’ve laid out a food-grade silicone mat to protect their feet from the bars. But as you might expect, the mat gets soiled and I wonder if this is worse for them than walking on the bars? I clean the mat every morning by running it under hot water and wiping it down with vinegar. And during the day I’ll do a quick clean up with a damp paper towel. But inevitably (since they poop every 30 seconds it seems) they are hopping around in their mess. I tried removing the loose toys to discourage them from going down there — but they go anyway (and they have SO much fun with those toys). Any advice about this? Thanks in advance!
