Winter is already coming, the weather is getting colder, and when we go out, we have to be careful not to get warm, so long as the wind is undesirable, it's bad to get cold. Not only humans, but also animals know how to keep warm.
There's one Internet friend who has a dog and two cats at home. The day the netizens went out to see them, and found out that they were all sleeping together. All they saw was dogs lying on the ground and two cats on its back. You think the dog's warm enough to get down there! It's good for a dog to use a cat for warmth, besides a little heavy.
For two cats, the dog is a mat, and for the dog, the cat is a blanket! Heating is mutual! They're freezing like this. Although they themselves have the ability to withstand the cold, it's pathetic to be frozen!
