Cats will go into heat in winter. Generally speaking, cats are in estrus from spring to autumn, but some cats are in estrus in winter. This is mainly because the estrus of female cats is related to the degree of light. Female cats are more likely to be in estrus in 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.

Solutions to cats in estrus:

1. If the cat owner wants to breed the cat, he can choose a mating partner when the cat is in estrus. Finding a mating partner for your cat can solve the cat's estrus problem, but you must be prepared to take care of the mother cat and her kittens after mating.

2. If the cat owner does not need to breed the cat, he can feed the cat an anti-estrus powder to suppress estrus. The cat can be fed when it starts to go into estrus. It should be taken continuously for 7-10 days, and it cannot be eaten on an empty stomach.

3. If the cat is very uncomfortable during the estrus stage, you can help the cat divert its attention and give the cat some toys to play with. You can also provide the cat with some fresh food and play brisk music to divert the cat's attention. .

4. Soothe the cat’s mood. If the cat is anxious and uneasy, you can stay with the cat. You can gently stroke the cat's back with your hands to make the cat feel the owner's company and caress.

5. Close doors and windows to prevent cats from getting lost. Cats in estrus can easily escape, so cat owners should pay attention to closing doors and windows to prevent the cat from getting lost.

6. If you don’t want your cat to suffer from the pain of estrus anymore and there is no need for breeding, you can sterilize your cat at the end of its estrus.
