Cats don't "stay" sitting even when I don't initiate the right-click.

So I tamed all 11 cats, and had them all sitting, surrounding my settlement, and while I was going about my playthrough of mining - when once in a while, when I stop moving, one of my cats will appear in front of me, still sitting, but moved right in front of me.

I didn't mind this at first because maybe he was the straggler, but I specifically remember counting all 11 cat types sitting, and I stayed within Render Distance of my settlement.

 

I was fishing within my area and again, suddenly two cats from my settlement [not the same one as before,] decided to also teleport to me, still sitting, but teleported to me. I wasn't certain anymore whether I was losing it, so I came back to my settlement to have 3 empty sitting spots where I had left these three cats sitting, and proceeded to let them sit back there. I'm checking if they'll randomly teleport to me again, but I hope that this gets fixed!
