Aren't they two different cats? Shouldn't the title be '*Are these cats real?'?
The first one reminds of one of those chocolate pots where half will be filled with brown chocolate and the other with dark chocolate.
poo and goo? pink and stink? blood and mud? jelly and smelly? bush and tush? slime and grime? snatch and hatch? ANDDD if you're snookered on the pink go for the brown bye bye!
