If your girlfriend forces you to look after her cat while she’s away you may as well make the most of the opportunity.
In this case, that meant turning kitty into a true party animal. And why not?!
This is, thankfully, just a joke. The cat didn’t really down alcohol and then start acting like a drunken lout. Cats don’t like the taste of alcohol. I know from experience.
This is just some guy entertaining himself by making an artistic video showing what it would like if cats really did get drunk as humans do most weekends.
The genital licking was unnecessary but then beggars can’t be choosers.
