From the day our pets met there's been a clear pecking order. I just assumed as Dexter grew he'd assert some dominance over the cats. Dexter is now pushing 50 pounds and is quite capable of eating a cat should the thought occur to him.
Alas, I heard whimpering coming from the kitchen last night. I walked in to discover Tom calmly guarding the water bowl. A fearful Dexter wouldn't get any closer.
Dexter continues to try to befriend Tom. It's slow going, but Dexter remains hopeful, if a little thirsty.
