Feline heartworm can be transmitted to humans. It is usually transmitted to humans by biting an infected cat and then biting a human. However, this bug does not survive and develop in the human body, so it is not harmful. However, it occasionally parasitizes in the lungs, body cavity or subcutaneous of the human body. Nodules and masses are formed at the site, causing organ and tissue dysfunction. Therefore, pet owners should do a good job in deworming and preventing mosquitoes when raising cats, especially after shaving their cats, try not to let them go out to avoid being bitten by mosquitoes and infected with heartworms.
