How can you be sure your cat is warm enough this winter? It’s kind of a complicated answer. Veterinarian Michael Arpino says, “Most cats handle cold temperatures very well. Cats who are used to spending a lot of time outdoors know when it’s time to come back in.” But with that said you should not leave an outdoor cat in the cold overnight, especially in extreme temperatures. Indoor cats can sometimes get cold as well, and the experts say you should keep a cozy place for them to snuggle up with a blanket or an insulated cat bed so they can avoid getting chilly. Arpino adds, “As a general rule of thumb, anything below 45 degrees Fahrenheit is too cold. If the temperature dips below freezing, they are at high risk of hypothermia if they are outside for extended periods of time.” If you’re concerned your cat might have hypothermia you should rush them to the vet.
