Those two both look like trouble on four paws!
They're very sweet actually. Found with their mum & two litter mates living in the trunk of an ancient yew near Newport. They were seriously socialised by someone who knew her onions when they were tiny (they're about 10 weeks now; we've had them a week) and as a result they love being handled and purr if you look at them
Tam's brother was even bigger, and Tam's a big chap already.
edit: I think they're both going to be fearsome hunters though...
edit2: living in a rented barn of a place with old tatty furniture (pending buying somewhere and replacing chairs, sofa etc) it's an ideal time to have kittens - and post Mille Cymru I'm around to look after them in the day (mostly)
