1. Squirrels Go Into Torpor
Instead of hibernating through the winter months, squirrels use their stores of nuts and periodical deep sleep states known as torpor to survive. They also eat as much as possible in the months beforehand to build body mass, which simultaneously acts as a reserve when food runs low and keeps them warm in freezing temperatures. When it gets too cold to venture out, squirrels huddle in dens, sometimes with other squirrels.2. Squirrels' Teeth Grow Throughout Their Lives
Like rats and mice, squirrels have teeth that grow throughout their lifespans. Squirrels typically have 22 teeth, four of which are incisors. The incisors are essential tools, which is why they keep growing — if they wore out, squirrels would be unable to do the following:- Defend themselves
- Shred bedding
- Crack nuts and seeds
3. Meat Is Part of the Squirrel Diet
Like humans, squirrels are omnivores. They'll happily consume any of the following:- Insects
- Small snakes
- Mice
- Lizards
- Warmth
- Safety
- Readily available food
4. They Can Live a Surprisingly Long Time
In the wild, squirrels have a very short lifespan, though the specifics vary by species. For example, ground squirrels can live up to four years in their natural habitat, while the eastern grey squirrel only lives two. However, this is generally due to predation, as squirrels have many natural predators:- Snakes
- Hawks
- Bobcats
- Coyotes
- Owls
