The reason cats go into estrus every few days is because they did not mate after the first estrus, and the intervals between estrus will become shorter and shorter, so they will go into estrus every few days. When this happens, you need to divert the cat's attention. You can give it some snacks or play with it. If that doesn't work, you can only choose to breed or neuter it. Otherwise, the cat will easily get pyometra over time, and it will also need to be treated at that time. surgery, and the risks are greater.
