Tamed Sitting Cats are teleporting to the player location

Tamed and Seated cats are teleporting to my location. This happened at some point while I was AFK for a few hours and from a distance of approximately 65 blocks away horizontally. The first screenshot attached below is the box that I am confining 10 seated cats. You can see that 3 of them remained in their current position inside the box, but in the second screenshot, you can see that 7 of them have teleported to my location still in their seated position.
