Cats are known to sometimes make strange sounds similar to bird chirping.
We explain why our mustachioed pets do this.
Chirping in cats is one of the manifestations of the hunting instinct.
The more a cat's hunting instinct is developed, the more often and loudly it will chirp.
Cats generally chirp when they notice something they consider prey, such as when they watch birds fluttering outside the window.
Cats also sometimes chirp in anticipation of food or simply out of excitement.
