Anyone else's pets acting strangely the last 2-3 weeks?

So my 2 cats which I have had both for the last 12 years have both started acting weird over the last 2-3 weeks. Especially my male cat. He has become very vocal and has started sitting in our bathroom which he has never done. Our female when we lay down has started jumping up on our bed and just paces the perimeter of the bed, also being very vocal. My sisters dog who she has had for 7 years, has also started acting odd.

Just wondering if anyone has noticed new behavior with their pets as well.
