I often get asked by patients who have just entered peritoneal dialysis, “I have a cat (dog) that has been with me for many years, and I really don’t want to leave it. To keep or not to keep, this is really a question. People who have pets at home must have had the pleasant experience of having their moods transformed into a peaceful and relaxing one by stroking their backs. Animal therapy has been very popular abroad, and is valued for its ability to heal the mind and produce a therapeutic method to fight disease. The benefits of owning a pet are 1) to make you forget loneliness, say goodbye to powerlessness, sweep away tension and stress, increase smiling faces, and keep your personality cheerful; 2) to lower blood pressure, reduce pain, lower cholesterol, prevent strokes, and stabilize blood sugar levels in diabetics; 3) to prevent allergies and improve immunity in children; 4) to become a caring person and not be defeated by a society with deviant values; 5) to understand the importance of life. 6.Help people to expand their social life, pets are the best start for friends to talk, the friendship circle can be extended to other pet lovers, and can also prevent parent-child relationship breakup; 7.Get out and become active, the phenomenon of insufficient exercise naturally eliminated; 8.Be able to have a normal regular life, weight loss effect multiplied; 9.Prevent chronic diseases caused by poor living habits. I am also a pet lover, traditional pets have had many, life and death countless times, know how hard it is to be separated from their partners. However, from a doctor’s point of view, and certainly from the point of view of patient treatment safety, the doctor’s view is very clear: “It is best not to have pets if you can”. But the pets here are those close to their owners, furry creatures. If you like aquatic creatures (fish, shrimp, turtles), reptiles or amphibians (chameleons, lizards, snakes, snails, salamanders), arthropods or insects (spiders, scorpions, caddisflies), mammals (hedgehogs, hairless dogs and cats), you can still keep them. Traditional pets, such as dogs and cats, have a wide range of activities and are prone to staining many microorganisms (bacteria, viruses, fungi) on their hair. Animal hair is fine and can fly around in space without being noticed, causing contamination. For a patient on peritoneal dialysis, this scattered hair will undoubtedly increase the risk of infection. Therefore, patients are advised not to keep hairball pets such as cats, dogs, mink, pet rats, and rabbits as much as possible. However, peritoneal dialysis patients should not be angry with their pets if they get peritonitis from keeping them, after all, shedding is the nature of pets, they have to change their hair whether you get sick or not, the key question is whether the owner is a clean person and can follow the requirements strictly. If you have to have a pet, we have a few suggestions: have your family take care of your pet’s daily life; your pet needs to be checked regularly at the vet for skin diseases; comb your pet’s hair daily and dispose of it properly; change special clothing (contaminated clothing) when playing with your pet to protect your abdominal dialysis tube, and change your clothes (semi-contaminated clothing) and wash your hands after touching your pet Keep pets out of the room where the laparoscopy is performed and disinfect the room more thoroughly; keep a single operating gown (clean gown) in the laparoscopy room to minimize the impact of pet hair; be sure to wash your hands strictly and wear a mask and hat before the operation. If you really love your pet and can do all of the above to save yourself from peritonitis, then take good care of it and let it keep you company; if you really love your pet but you can’t do all of these things, don’t keep it so that it doesn’t get the reputation of being the “culprit” of peritonitis for you. After all, pets only give you the most selfless love and tolerance with their lives, and it is only the patient’s own carelessness that causes peritonitis.
