Monkeys laugh
Did you know that?
Primates laugh
As some rodents do too
Rats laugh
I very high pitched squeal
Unheard to human ears
You can tickle a rat
And it will laugh
You can't tickle a dog
Or a cat
But dogs like a good petting
And Cats a back scratch
Purrrrr.
What gets you purring...
Me, a good vintage glass of wine
Good friends
And life!
