Cat Sandwich 

Unlike its name might suggest, a cat sandwich is in fact entirely free from small feline creatures.
The "Cat" in a Cat Sandwich is actually just an acronym for the sandwich's filling; Cheese, Avocado and Tomato. (With pepper on top for extra deliciousness)

The fillings should all be sliced, with the cheese on the bottom, tomato in the middle and avocado on top.

Sam: Christ I sure am hungry. I could go for a fresh Cat Sandwich right now!

Rosie: That's sick! You eat poor little kitties!?

Sam: No, silly ho! It's a cheese-avocado-tomato sandwich.

Rosie: Eww, avocado...

Cat in a pool 

Trying to get your nuts in a girls ass while getting your penis in her pussy at the same time. Like a Dog in a bathtub, but much harder to do.

We tried the Dog in a Bath Tub, but that wasn't crazy enough fou us, so we tried the Cat in a Pool.

cat napping 

A common sexual practice.
This involves taking naps between acts of sexual intercourse in order to recover and gain an energy boost for the next session. Couples may drift between sleeping and sexual intercourse numerous times with no verbal communication or other activities outside of the bedroom.
This is probably the most productive way a couple could spend a sunday. I.e. in bed and fucking.

Joe: How was your weekend man?

Peter: Pretty mad... spent all of Saturday and Sunday cat napping with the missus.

Joe: Awesome... wish I had a cat........

Peter: ?
