About eight months. Blue male cats usually start to go into estrus around eight months old, and the estrus period lasts about a week. Larger cats will come into heat slightly later than smaller cats. But it’s also related to the blue cat’s living environment and feeding habits. For example, if a growing blue cat is stimulated by a female blue cat for a long time, the estrus period will be advanced. When a cat is in heat, it will urinate everywhere. The smell of urine is particularly strong, and the cat becomes more aggressive and wants to run out to find the female cat. Generally, the discomfort caused by blue cats in heat can be alleviated by comforting and diverting attention.

Blue cat estrus performance:

1. The cat usually urinates in the litter box, but suddenly urinates everywhere in the house. It may be in estrus. During estrus, male cats will urinate randomly to mark their territory and vent their anger. If you find that your cat is urinating indiscriminately, clean and disinfect it in time to prevent the cat from urinating in the same place.

2. During estrus, male cats will find ways to run away from home to find female cats to mate with, so they will engage in some dangerous behaviors, such as jumping out of windows. Once some male cats escape, they never come home again. Pet owners must seal windows and lock doors and windows to prevent cats from running away from home and causing accidents.

3. When male cats are in heat, they will roll around or twist their bodies. Some will howl loudly, raise their tails high and shake rapidly.

4. Male cats in estrus will also surround female cats and fight with other male cats. The frequency of fights will also increase, and their temper will also become violent and irritable.
