Yes, they do. We have an outdoor cat with a bad attitude towards litter boxes, and now a bowel condition. He gets way more fodder than the inside cats. He also has a heated cathouse that gets checked often in cold weather. We've upped his rations and they're going eaten. In summer, it is about half.
I also think there's a response to short days that causes cats to try to pile on some insulation if they're allowed, even if the temperature where they are is constant. (stories omitted) Dogs'll do it too.
It did occur to me a few weeks ago to wonder whether Perrine would need to eat more to maintain her body temperature in such a chilly house, but I forgot to ask.
