Cot is the kitty laying down and Cyle is the one sitting in the foreground. Cyle loves to (even though he seems irritated when Cot comes after him) egg Cot on. I've watched him strut by Cot and then run off as if to say, go ahead and chase me. You can see in the picture, that it appears he's looking back almost saying 'catch me if you can'.
So, in this next picture, it's as if he's saying 'what......I don't see you there'.
Cot appears to nonchalantly notice Cyle is there. And then in this last picture, Cyle is checking out from the other direction, to see if Cot has taken the bait yet.
There are a lot of times you can hear the sound of wild horses running through the house; it's Cyle with Cot in hot pursuit! Cyle will hiss and growl, and then keep on playing. Cot never hisses or growls at his brother. They are funny to watch, for sure. I hope you enjoyed this! Have a purrrr-fect day!
