I have 1 so far for dexter & he loves it. He swims through it & sleeps in it. I'm thinking of getting one for my little girl Penelope. My other guys prefer their hammocks. No probs with the paint here either.
This is what I do for one of my guys instead of buying a log... I cut the bottom off of a medium plastic cup (so there are no jagged edges). Since it sinks, I cut a strip of styrofoam cup and put that length-wise in the plastic cup. It keeps the cup floating and Dane LOVES it - he builds his bubble nests in there and hides in it during the day. He doesn't sleep in it though.
