The female cat, about eight months old, was vaccinated the day before yesterday and has been barking in pain for the past two days. Is it a normal reaction after vaccination? Or in heat?
It has nothing to do with the vaccine, but it's estrus. Don't feed chickens and fish, put plastic bags at home. These things contain estrogen, which is easy to cause estrus. Just feed ordinary cat food. If you cook your own cat rice, you can only use pork, which will reduce the chance of estrus by more than half and let you worry.
