Sleeping with a cat comes with health risks.
1. Disrupted sleep

Cats are champion sleepers, clocking around 15 hours a day, but their sleep cycles aren’t the same as ours.
A cat who snoozes the day away might be ready to compete in the Kitty Olympics come 2am, racing around the room and leaping off furniture.
Athletic feats aside, cats may snore, scratch or simply prod you for attention during your sleeping hours, which can take a toll on your ability to get good rest, and leave you feeling drowsy and sluggish the next day.
One U.S, Mayo Clinic Sleep Disorders study found that more than 20 per cent of patients who sleep with their pets say the animals disturb their sleep.
2. Exposure to litter box debris

Litter boxes are dirty places, and cats’ paws can capture bits of cat litter and waste, which can end up in your bed.
While rubber mats placed outside the litter box can cut down on the amount of litter and waste that gets tracked through the house, you can’t eliminate it entirely from your bed without making the bed a cat-free zone.
Here’s the best way to clean your house top to bottom if you own pets.
3. Allergies and asthma

Up to 30 per cent of people have some kind of allergic reaction to cats and dogs, according to the Asthma and Allergy Foundation of America, and allergies to cats are twice as common as reactions to dogs, experts say.
Doctors recommend removing cats from the home if someone is allergic, but there are less drastic measures you can take to ease allergy and asthma suffering – such as nose sprays or allergy shots.
By keeping your bedroom door closed and using a good HEPA filter, you can also eliminate allergy and asthma triggers while you’re sleeping.
