Thanks everyone.Yes they really are great together.Benson also loves Rufus(The black kitten)as well.He loves playing with all the kittens.They all did get as big as the adults except for Sara.She's so Tiny I need to give her high cal gel.She's so skinny I worry about her.Marshall is small too.And Bowie because he's so picky about food.
The rest are too big.
