Oh, Peanut! You poor thing!
He was lying on top of Ted's cage annex with Squash, stretched out on his side, oozing, oozing over the edge....
And fell with a massive THUD flat on his massive side.
And lay there looking stunned for a bit. Then rolled onto his back ("I meant to do that"), then sat up, and has just leaped back up to snuggle into his buddy, purring loudly.
Some few but sufficient inches from the edge.
