I agree with you, up to a point. Size does come into it if you are both fighting 'gamely' though. It is difficult to get a cat into a travel box because you don't want to hurt it. If you grabbed it when it tried to scratch you, swung it head first against the wall a couple of times as hard as you could, and then flung it into the travel box, then you would probably find it a much more hassle free task. (You'd probably still get scratched a few times though)Size is not important (oo-er missus ) it's how 'game' something is, ever tried to get a cat that ain't up for co-operating into a travel box....jayzuz, vicious lil blighters, i could only imagine a wild animal being cornered and fighting it out....very messy!
I am not, however, suggesting that you try this!!
