Everyone is doing great, everyone learned to purr when picked up. Their characters are all pretty different.
Number One is an active explorer who sleeps in the weirdest positions and loves playing with humans. He jumps on mom's back while she cleans their litterboxes and plays with the strings on my pants.
Number Two is a fat fluffy philosopher who doesn't purr loudly, but enjoys being petted and likes belly rubs while lying on his back on my lap.
Tiger Grey is the fastest, most active of the gang, he often escapes from the cat room and is really good at it. He will jump on my lap for pets when he is in the mood.
Tiger Brown is a bit calmer and not as mischievous as his identical tween, but his purr is as loud.
The calico girl is brave and reckless, wouldn't expect anything else from a tiny girl growing up with four bigger brothers. She likes sitting on my lap, but she'll try to play and bite at the same time. She climbs to the top of the playpen constantly and makes impressive long jumps from one roof to another. And she is the one who will smack the vacuum with her tiny paw while her brothers step back. She looks fluffy too.
