My younger cat has been guarding me for a good month now. She sleeps at the end of the bed all night watching. When I'm relaxing on the couch, she put her head on my legs and stay there until I get up.
I would expect this behaviour from my older cat, but the younger one is hyper and has the attention span of a flea.
She always sniffing at me like she's making sure I still smell right. It has me wondering if there's a pg smell and since everyone gets upset after the smell goes away, she's protecting me.
