Helen the one I have for Lexy is big enough for two, its sturdy so it won't put pressure on the bed or the radiator. If it can hold Lexy, it can hold both boys comfortably.
Thanks Ruth but have you seen how long Riley is?
When I hold him lengthways in my arms I struggle to get through doors, he's so long that I can't hold him upright like a normal cat as my arms aren't long enough so his legs just dangle down!
Riley has just, begrudgingly, got in his purple spotty bed that they had from babies, maybe it'll encourage him to use it a bit more!
Gill, mine sticks out 35 cm - Lexy's one looks a slightly different style to mine, mine is more like a hammock - less rigid.
Here's Riley in it the other day...
and LuLu it in a few mins ago with Riley sulking on the floor near him
