Yeah, Snoopy growls a lot just before feeding time. He tries to secure himself the place at the front of the queue. Every few days they get some carrot or apple pieces, and then Penny and Luna usually grab a piece and run off. Penny sometimes hops around for more than a minute until she has found a secure spot to eat.
And then there is the fact that even though there are lots of greens or parsley leaves, the one that is in Snoopy's mouth is usually the best, so the girls try to steal it from his mouth. Looks like they are kissing, very funny.
