why my cat sleep all the time?

I have had many cats, and all of them loved to sleep! It's pretty normal. I have 2 here now who sleep all the time.

Cats are typically nocturnal in the wild. So house cats tend to be more active, too... My cats (Josie and Spec) are rarely seen during the day (they're either asleep or hiding from my girls). Then as soon as we all get into bed they start running around like crazy. It really amusing. Well for me, but not so much the downstairs neighbor.... Older cats tend to sleep longer, too. Last year I lost my Sprite (she was 20 years old)....

They can seep on average about 19 hours a day, thats totally normal..But if you do have any concerns at all, it dosnt hurt to get it checked by the vet..

Cats sleep 18-20 hours a day. This is normal. In the wild, if a cat gets a meal, they stop hunting & sleep to conserve energy. This is why cats have those incredible bursts of speed when they need it. They have little stamina, but sleep to conserve calories. We can take the cat out of the wild, but we can't really change their nature. Honestly, we have domesticated animals who's nature is to our benifit, horses for pulling & riding, dogs for tracking, running down prey and retrieving objects, sheep for wool and meat. Cats came into our homes to hunt rodents, quick, short bursts of speed & alert senses. You will find your cat more likely to be awake at night too, they are more nocturnal because their prey is primarily nocturnal.

Cats sleep all day so they can stay up all night. Thats because cats are nocternal. Owls and Bats and Flying Squirrels are other examples of nocternal creatures.

cats can sleep 18 hours a day--- but if you have noticed a change in the cat's behavior pattern take him or her to the vet

That's his or her nature. Cats do tend to sleep for much of the day. My Columbus and Waffles sleep a lot, while Mimi is up most of the time. If you are still in doubt about your cat, you should consider taking him or her to the vet for a general check-up. You'll have greater peace of mind.
