you bet they are. all currently charging around in the living room and outside... infact they spend most of the time outside and are all eating solids... about 2 months old now. still yet to scale the fence... which is great cos all the whilst they stay in my back yard i should be all good with neighbours. I have had a few uncomfirmed takers for homes for these little guys... who i have named after the planets.
Mercury: striped ginger kitten... first to eat solids.
Mars: Second to eat solids... also ginger but not as stripy
Jupiter: Lightish grey... biggest kitten of group
Saturn: small and darker grey kitten... last on solids... quite timid
both grey kittens are timid... Mercury is the least timid
