To start with....
I was adopted by 2 black cats who are now living with my mum (they are already teenagers in human years).
Where I live now I was also adopted by a black cat.
Other than cats, I've had a rabbit (I like rabbits - but they are so not compatible with cables...) and a rat (who was very smart). But I don't really think I want to live without cats.
And yes, based on my experience, cats love sleeping on Mac keyboards (and rabbits.. I rather keep them away from my computer equipment totally). Now time to see what other iPets we have around...
Or wait as the others have added pics to theirs, here my darlings without the links
Musti (the iBook is for the scale..)
