Idk the one on the floor started grabbing socks one day and the one on the bed we got a year later and learned to grab socks from him.

They don’t pull and bite the socks they usually just grab it from my feet and carry it around like a child.

Hopefully block chain technology will die off and become irrelevant in a couple of years. So far any attempt at using it seems to make a dumpster fire.

I have a cavalier as well and he looks just like yours.
