Awwww, Tubby you are such a sweet big brother to Peanut but don't be so rough on her.
Samantha isn't allowed to lick her little sisters, I'm afraid she may try to eat them!

I know what you mean about the lick, lick, chew, chew grooming pattern.
My daughter and I love to watch Samantha groom herself and we say "lick, lick, lick, chew, chew, chew" as she does it then she stops and glares at us!

Tubby, Samantha says you are welcome to come over and lick her anytime that Peanut isn't in the mood.
