There's a reason your cat always seems so angry BuzzHead, but it's not just because you named him Mr. Tinkles.

A new study out of the University of Lisbon in Portugal has come to the epic conclusion that cats simply hate rock music. Especially AC/DC.

According to the researchers, they played AC/DC's hit song "Thunderstruck" to a group of 12 cats and observed their reactions.

The results were simple. Cat's hate AC/DC.

During the course of the song, they noticed that the cat's breathing increased and their pupils dilated, both of which are signs of stress.

Meanwhile, the same group of cats were exposed to the classical composition "Adagio For Strings" by Samuel Barber, which completely calmed the cats.

Dr. Miguel Carreira, a veterinarian and lead researcher on the project, stated that "during consultations I have noticed, for example, that most cats like classical music, particularly George Handel compositions, and become more calm, confident and tolerant throughout the clinical evaluation."

Researchers also played some pop music for the cats, which didn't seem to have much of an effect. The end result, according to researchers, is that this new information could help veterinarians across the world perform safer surgeries, at least when it comes to cats.

So if you're  tired of dealing with your girlfriend's rude and intrusive feline companion, just crank up The Buzz and leave the window open. The rest should work itself out.
