The Health Benefits of Owning Pets

Do you count one or more dogs, cats, fish, reptiles, birds, or other animals as part of your family? Almost 7 out of 10 US households include at least 1 pet, according to the Insurance Information Institute. Many people love their non-human friends because they offer companionship. Our pets can also increase our opportunities for socialization, exercise, and outdoor activities.

According to the Centers for Disease Control and Prevention, pets can have positive effects on our physical health. They can decrease our blood pressure, cholesterol levels, and triglyceride levels.

But just like people, pets sometimes carry germs that can make us sick. That’s why it’s important to take your pet for regular veterinarian checkups to keep them healthy. You should also practice good hygiene around your pets to avoid transferring germs. This is especially important for people with weaker immune systems, including cancer patients undergoing chemotherapy.

Stay Healthy during Chemo

Your pets can be an important source of emotional support while you receive chemotherapy. But some pets – including reptiles, chickens, ducks, hamsters, gerbils, mice, guinea pigs, and ferrets – are just not safe while you’re in cancer treatment. Most healthy inside cats and dogs are safe, but it’s still important to protect yourself from your pets’ germs while your immune system is weaker than usual. Talk to your cancer care team and your veterinarian about your pets, and the best way to care for them while you’re in treatment.

Precautions you may be advised to take include:

  • Avoiding scratches and bites. Get your pet’s claws trimmed often to make scratches less likely. If you are scratched or bitten, clean the area and call your doctor.
  • Avoiding pet urine and feces. Wear gloves when you clean up waste from outside or from a litter box. Wash your hands as soon as you’re done. Better yet, ask a friend or relative to handle this chore.
  • Washing your hands with soap and water after playing with, caring for, or petting animals, especially before preparing or eating food and drink
  • Not allowing your pet to lick your mouth, open cuts, or wounds
  • Keeping your pet clean, and keeping regular veterinary appointments for a healthy pet
  • Getting a new pet when you have cancer is usually not recommended.

Children With cancer

Children who are too young to follow these precautions should not be near pets. Children tend to be at higher risk for infection from pets than adults, because they’re more likely to crawl on the floor with the pet and put things in their mouths. If your child has a weak immune system or might be getting a bone marrow or stem cell transplant, it’s even more important for them to stay away from pets.

  • Adults should supervise the time a child spends with pets.
  • Don’t allow kissing, food sharing, or rough play.
  • Don’t let children put the pet’s toys or their own fingers in their mouths. Be sure the child’s hands are washed thoroughly afterward, and again before eating, drinking, or taking medicines.
  • Be sure your child’s cancer team knows about your pet and ask them if there are any special precautions you need to take.
  • Keep your child away from strays, wild animals, petting zoos, and other people’s pets.
