Rather than move the bricks from inside (which is awkward anyhow), better to step outside facing the cat feeders and move the bricks there. Also, now that each feeder’s 4 bricks have been glued together (I used DAP Alex Plus caulk), pretty easy to just pick up and move the blocks.

Doesn’t seem that long ago I glued four bricks together to make a block! Ever since, the raccoons haven’t toppled the cat feeders, so I’ll take that as a win. In addition to the 16 lb weight, I imagine brick isn’t a texture raccoons like to come in contact with their claws.
