I have to agree...keep an eye out...what is
not normal has
some meaning even if you never actually realize what it was.
I have seen many animals, cats and dogs, do some apparently weird 'protection' behavior. I had 3 kitties build a triangular invisible 'fence' around me one night...all facing away as if they were watching out for something. I'd step out of their 'fence' and they'd adjust and build a new 'fence' keping me dead in the middle. It was so odd, I called DH from the yard on my cell and he came out of the house and watched. Then, when he got to me, he stayed out of their 'fence' and they rebuilt it around both of us. We tested this behavior for about 30 minutes together and they continued rebuilding every time we breached their invisible fence. To this day, I have no idea what they were really all about that night.
Good boy, Pnut!
