I have one of those, it thinks it's a alarm clock and starts meowing about that same time and or trying to shred the other cat.
I thought it was for me to get up but the wife went out of town for a week
It stopped the entire time or it knew it's life expectancy or living conditions might be in jeopardy.
The outside semi feral cats are more fun, they follow me into the woods run in front of me and roll over and will do that on command but your not allowed to touch.
They hunt and stalk, sometimes in packs deer included (they have yet to get one) funny shit.
