Muffin gained some chubbiness the past two winters, but this Fall her really bulked up. I knew we were in for a harsh winter when I saw how much weight he gained and how thick his fur became. I live in Western PA and we've had 3 snowfalls and numerous days where the temperature has been in the mid teens. He won't come inside, but he has a nice cedar wood, insulated house on my porch which he uses, and he's well fed. I'm wondering, though, if I should be concerned about how big he's gotten? Should I switch him to weight management food? I leave Purina Pro Plan Smart Blend Chicken dry food out for him during daylight hours (he loves it) and wet food at least twice a day (Fancy Feast, Blue, or homemade chicken breast) but he doesn't eat for 10-12 hours during the nite. I know that I'm the only one on my block currently who is feeding him, though it's possible someone else on another block may be feeding him (he's such a cutie) and I'm not feeding him any differently than I have for the past two weeks. He seems healthy. Should I just continue to feed him as I have been in light of the very cold weather and snow?
