More people may soon be investing in cat food as a vaccine has been developed that treats people who are allergic to felines.
Researchers at McMaster University have developed the vaccine that is "safe and effective" and has almost no side effects.
Mark Larche, a professor in the Department of Medicine in the Michael G. DeGroote School of Medicine and Canada Research Chair in Allergy and Immune Tolerance, has spent ten years developing the vaccine.
The vaccine, which is known as 'peptide immunotherapy', is given into the skin. At present, between four and eight doses may be required a year.
According to the report, between eight and ten per cent of the population are allergic to cats.
This vaccine may mean sufferers can get a pet cat and enjoy their feline company.
US songstress Katy Perry recently revealed that she was "obsessed" with her three cats.
She explained that she feels akin to her cats, saying: "Cats are like, 'You have to earn my affection'. And I really associate myself with that."
