Well, I had his pool from last year inflated, then Mackey decided to hop in and put holes in one of the rings - argh! I tried to patch it up - it just wasn't enough.
I can't complain too much - they're not very expensive - but the other one was from G'ma and G'pa.
He wasn't too sure at the beginning - but got the hang of it soon - and, of course, didn't want to get out. I imagine that we'll spend lots of afternoons here. Thankfully, our balcony is all shade in the afternoon!
