Jennifer Lawrence recently got herself a new cat, but there are many things she still hasn’t figured out about it. While stopping by Ellen (on an episode that airs Wednesday), she revealed that she got the cat thinking it was male, but it was actually a female! The cat even had a collar that said Oliver, but she’s since named it Cleo. However, being the pet lover that she is, Ellen DeGeneres gave Jen some insight as to the cat’s gender thanks to its color. Also, Ellen explained why her cat keeps peeing on her bed (in a house that she was only renting — LOL!). Who knew Ellen was such a pet expert?! Watch the video above!
