The protruding, red and swollen anus of kittens may be caused by constipation or parasitic infection, or it may be anal gland problems such as anal adenitis and prolapse caused by severe diarrhea. No matter what the situation is, you must pay attention to cleaning and disinfecting the kitten's anus and pay attention to hygiene to avoid infection. Then take the kitten to the pet hospital for treatment as soon as possible, and treat it based on the cause, so as not to delay the best treatment opportunity. .

　1. Constipation

When a kitten is constipated, the continued struggle to defecate will cause the anus to bulge, become red and swollen. At this time, the owner can check the cat's stool to see if it is dry. If the stool is indeed dry, the owner can feed the kitten some probiotics and food with higher water content. After the cat's constipation is improved, the anus will be swollen and recovered. . However, if the kitten’s anus is severely protruding and the intestines can be seen, it needs to be sent to a doctor for treatment in time.

　2. Parasitic infection

If the owner does not deworm the kitten, and the kitten is infected with internal parasites such as coccidia and trichomonas, it will suffer from diarrhea. If the diarrhea continues, the kitten will have a protruding, red and swollen anus. At this time, the owner can check the cat's feces to see if there are white parasites. If there are, it means there are more parasites in the cat's body. At this moment, you need to take the cat to the pet hospital for a fecal examination as soon as possible, and then deworm it.

3. Anal gland problems

When a kitten has severe diarrhea, it is easy to suffer from anal gland problems such as anal adenitis and prolapse, causing the anus to protrude, become red and swollen. If it is not serious, you can first clean the prolapsed area with physiological saline, and use pet-specific anti-inflammatory drugs to keep the prolapsed area clean and hygienic. But if the anal prolapse is severe, you need to take the kitten to a pet hospital for surgery as soon as possible.
