The past few nights, Oliver will get into this mode while he's chillin on my low dresser and all of a sudden start wildly chasing his tail! He's 4 years old, haha, so I was pretty sure he realized it was part of his body... he lays there like flipping the tip of his tail, like he'll stop and go, and he looks at it like he's hunting a bug! I just go "don't you make the connection that you're the one causing the tail to move?!" Then he'll attempt to pounce on his tail, which turns into running in circles (mind you, this is all on top of a polished dresser)... sometimes he'll get his tail up between his legs, so it's coming up to his face under his belly, and watch it twitch and I'll warn him "that's part of your body, it's gonna hurt when you chomp!" but he does it anyway and then looks like "WHAT THE H*LL WAS THAT?!"... I'm just curious if there's ANY rhyme or reason to this suddenly odd behavior... it's not a problem or anything, just weird - he has PLENTY of toys and interaction time throughout the day and has been hunting lots of bugs and teasing the dog, so I know he's not bored....
