We've all heard the phrase.

"She's a crazy cat lady!"

Once women hit a certain age and are still single, society slaps a label of "she must have something wrong with her...that's why she has so many cats" on her. But as it turns out, science is here to tell us otherwise.

A recent study conducted by the University College London disputes past findings which suggest growing up with cats poses a higher risk of mental illness, or "craziness."

Past evidence has shown that cats carry T. Gonii, which is associated with schizophrenia. It also led researchers to believe children growing up with cats were more likely to develop a mental illness.

However, this new study fully disproves the old one.

"The message for cat owners is clear: there is no evidence that cats pose a risk to children's mental health," Dr. Francesca Solmi, the study's lead author, said in a news release. "In our study, initial unadjusted analyses suggested a small link between cat ownership and psychotic symptoms at age 13, but this turned out to be due to other factors."

The other factors included over-crowding in the home, and financial issues in the home.

But both studies can agree on one thing. Pregnant women need to be wary of T.Gondii which is carried by a lot of cats.

"There is good evidence that T. Gondii exposure during pregnancy can lead to serious birth defects and other health problems in children," said Dr. James Kirkbride (the study's senior author,) "As such, we recommend that pregnant women should continue to follow advice not to handle soiled cat litter in case it contains T. Gondii."

So there you have it. Being a "crazy cat lady" actually holds no scientific value. So stock up on furry friends, if that's what you want!
