It's a commonly accepted fact among cat owners, that our feline friends make their own schedules.
Whatever time of day they decide to head out on an adventure, they always seem to expect a human to be on call to let them back inside.
The politest pet
It seems this isn't the case for all cats, as 9-year-old RJ has recently shown.
The clever kitty has learnt how to get his owner's attention, in the most surprising way possible...
Nobody knows how he worked it out, but RJ asks to be let in by ringing the doorbell!
Clever cat
In a video captured for TikTok, Alyssa shows RJ reaching up to ring the bell, and then patiently waiting for the door to be opened.
He seems to get quite frustrated with the speed of his owner's arrival, meowing as he sits on the doorstep.
Alyssa admits her pet's new talent came as quite the shock, as she had no idea he had picked up on the bell. Viewers were also amazed, with one commenting, "so very polite and very clever". Another compared his skill to her own cat, who learnt to jump on the door handle to open the door.
