:I want to put a couple pvc perches in my vision cage without drilling big holes. Any tips on making or buying some kind of brackets and mounting them?
Get some plastic closet rod holders and a tube of clear silicone sealant. Squirt a little dab on the rod holder and stick it to the side. The holders cost about $2 pr. and the silicone is about $3. Believe me, it will hold a lot of weight. You can find this at Wal-mart, Lowe's or Homo Depot.
