Oh my, both my cats, Tessa a 3 year old Tonkinese and Smudge, a 1 year old Siamese mix, are VERY affected by full moons. They started two days ago, it’s getting worse, and it will last at least two days after. I’m not looking for advice, just sharing my woe. They are currently chasing each other at 100 mph and just generally running amok. It’s like the normal cat “crazies” times 500!! Ahhhh full moons.
