I sing
"Hey there ivy cat, running through the fields like she's a cat, catching all the mice like she's a cat!!"
And for Betsy the fluffy one who likes to pet her fur blow in front of the fan I sing
"If you liked it then you should have put your fluff on it, Betsy boo oo oo oo oo oo oo oo oo ooh"
I get the same looks from the family when I do that.
To be honest I get the same looks from the cats too.
