Awwwwww

my kittens are so cute. They were both snuggled up asleep earlier and i couldn't resist saying hello to them both, stated giving Ginny a belly rub so she rolled over to show off more belly

when penguin suddenly started rooting around searching for a teat

she was pawing at Ginny and everything, thankfully Ginny didn't seem phased, and just jet her get on with it.

I'm pretty sure i saw Penguin do the same a few days ago too, so it seems to be a habit for her.
Anyone else had kittens do this?
