I second the tesco one, I bought mine from elsewhere and they were £25 + postage so that's a real bargain
They have seatbelt straps, stroking holes and open at both ends
like a shell sorry forgot you're a bloke, like the car in Back to the future
I always get admiring glances when the boys are at the vets, today when the nurse brought them out to me they were in the same carrier (they had arrived in one each) I said that I had another carrier too and she said that she thought it looked like a double buggy so she put them both in together, how cute is that
I would recommend getting two carriers though, one is fine for when they are babies but trying to a) get two full grown cats in one carrier without the other one popping out while you try and put number 2 in is virtually impossible and b) they will be bl00dy heavy!
