A cat's days can be lonely and dull. Thanks to a new furry friend, however, this feline's everyday life is now filled with fun and games, and a viral video has captured their sweet story!

The heartwarming clip shared on TikTok begins with a bored orange cat obviously looking for something to do.

The curious furball is filmed gazing out of the window, lounging on the floor, and half-heartedly playing with toys, but nothing seems to really captivate her.

Then, however, there's a cut, and the kitty's monotonous life takes a wonderful turn: a second cat moves in!
