Nini likes to bop over her water bowl so she can watch the water run down the floor and pat it with her paw. Nene kneads my arm to pieces, then falls asleep cuddling it.
If I don't get up at the designated time, one of them (probably Nene) knocks over stuff on purpose, but if they try to get me up before our usual time and I refuse, they'll accept that without taking their revenge.
I play 'peep-bo' with Nene; I pop my head around the door when she's inside a room, and by the third time she can't take it anymore and runs at me going 'MRRRRRR!'
Nini plays fetch with her mousie and when she wants something specially, her miaow goes 'rrr-aw-rrw-WEH!'
I love them madly.
