Cats do not often sit in a human pose, using their "butt" as support.
It is unlikely that such a pose is comfortable for a pet - let's figure out why an animal voluntarily takes such a pose.
First of all, they do this to make washing more convenient – it turns out that a cat spends about 30% of its time washing itself.
Sometimes a cat is simply hot, so it rolls over onto its back or leans against the ground to expose its belly to the cool air.
It happens that the animal has taken such a position and simply does not want to turn over due to banal laziness, not wanting to make unnecessary movements.
It happens that the only bad reason may be pain - if it hurts for your pet to lie in a normal position, then you need to urgently contact a veterinarian.
Some cats love to be the center of attention, and they try to take an interesting position to be played with. Treat your pet, which he will definitely like.
