Yes, cats will go into heat in winter. Starting in late winter every year, spring and autumn are the main estrus and mating seasons for cats. A female cat's estrus is related to the degree of light. Female cats are more likely to be in estrus during seasons with longer sunshine hours. However, cats raised at home will also be illuminated at night, so they will also go into estrus in winter during the non-breeding season. As for male cats, they basically do not have an estrus cycle. They are mainly stimulated by the pheromones secreted by female cats when they are in estrus.

Measures to deal with cats in heat:

1. Close the doors and windows. Cats in estrus are particularly likely to run out. Many domestic cats do not have the ability to survive in the wild. Once they go out, they cannot come back, so be sure to close the doors and windows at home.

2. Supplement nutrition. Because the cat becomes mentally stressed during estrus, which affects appetite, the cat’s resistance will be reduced. Try to choose a high-protein diet, such as a meat can that can be rehydrated at the same time, or rehydrated and fed some freeze-dried raw meat, which is more palatable than staple dry food.

3. Pay more attention and comfort, such as touching the head and scratching the itch, to relieve the cat's mood. You can cuddle it to sleep at night, or put it in the cat bag and put it in the bag. Wherever you can reach it, when it barks, put your hand into the cat's bag to touch and comfort it. Be careful not to touch the cat's sensitive butt.

4. Do not use the cotton swab method, and do not touch the cat’s butt with cotton swabs or other items. It is unhygienic and can easily bring in bacteria, and can easily lead to false pregnancy and pathological changes.
