What she lacked in size or weight, she made up for by being astoundingly cooperative.
And she's still pretty cooperative, barely complaining about travelling by bicycle trailer, although she's made up the weight and volume bit by quite a way, being about three times heavier now!
It'll be interesting in a weeks time, to see how she and Kai get on, sharing a carrier to the cattery! If things become daft, I'll do it in two goes, it's only a couple of miles to the cattery, but they should easily fit in the larger carrier, assuming I can get it on the trailer OK.
That may not be true in the future, depending on exactly how big she gets. Kai is already a medium sized cat. If she gets big, I suspect that there won't be room for two of them!
