Rei is quite the little mischief-maker in the yard. He apparently feels that anything within reach is fair game to be a chew toy--including, as I discovered, a bunch of cables that were attached to the exterior of the house. O_O He chewed one of them completely through...thank goodness it wasn't an electrical wire!
I grabbed a roll of duct tape to affix all the wires flat against the side of the house so they wouldn't be such a temptation. (Hopefully I can come up with a more permanent solution soon.) While I was doing that, I came across a monarch butterfly chrysalis attached to the side of the house near the wires. That means at least one of the caterpillars has survived, yay!
