An opportunist is someone or something that seeks out new environments and situations in case there’s a good chance of something good happening. Ferrets are opportunists, which means they constantly have their eyes and (espicially) their ears open. They take notes and store the info in their small brains for later use.
The main way I’ve observed my ferrets making use of their stored data is in remembering sounds. The sound of the spoon scraping against the bowl is the sound of an upcoming snack of leftovers. The sound of the closet door opening is possibility of entering the forbidden area. The sound of the fridge opening is yet another chance to explore this mysterious place with so many wonderful smells.
What makes your pet ferret such a great pet is his attunement to your activities. Ferrets will adjust their sleeping patterns so they’re awake when you are. They’ll greet you every morning if they’ve observed that good treats are given out first thing of the day. They’ll watch you intently to get your attention if the food bowl is low, or if the water needs changing. Or sometimes they’re watching you for signs of a good play session about to begin.
This is bun, watching me. He’s taking notes inside his head and will later use it against me!
