Why do cats scream on winter nights? Cats yell on winter nights probably because they look for mates. Cats will attract cats of the opposite sex and compete for territory by moaning. They may also seek security or emotional comfort in their calls.
Cats will have estrus three times a year, which is alternated in winter and spring, early summer and autumn, and each estrus will last about 2 to 4 days. So it is very likely that cats are in heat when they scream in winter. In addition to chirping, cats will often rub around, stick their butts, and roll around on the ground. At this time, the owner will not only breed the cat, but also divert attention, use banned powder, and sterilize it.
