What happens to a squirrel's breathing rate during hibernation?

This is a science question that was my homework. Can somebody please answer my question!!!!!!!What happens to a squirrel's breathing rate during hibernation?
When ground squirrels hibernate, they go into their dens to sleep through the cold of winter. They usually hibernate five to six months of the year. Their body temperatures drop so that they are only about one or two degrees higher than the temperature outside. The body temperature drops below the freezing point of water. Their breathing and heart beats slow down. A ground squirrel鈥檚 heart will beat only a few times in a minute during hibernation. Every week or so, the squirrels wake up for about 12-20 hours and then go into hibernation again. Some ground squirrels don't hibernate if they are in climates where the winters don't get too cold. Hibernation is the animal's way to adapt to things it can't change like weather or not having food available.What happens to a squirrel's breathing rate during hibernation?
the breathing rate will probably go down like all animals during sleep.
squirrels hibernate during winter? there's something wrong with the ones around my house then. because i thought they stored acorns and stuff because there would be very little food available to them. Unlike at my house, where we have food available to them at all times. so i'm confused.
the rate decreases
the breathing slows down just like most of the vital systems
