Plot twist: I'm suddenly a grandparent to 4

So apparently my cat Luna has been keeping secrets. Came home from work yesterday to find FOUR tiny potatoes squeaking in my closet. How did I miss that she was pregnant?? The kittens are all completely different colors too - one's pure black like Luna, one's orange tabby, one's calico, and one looks like cookies and cream. It's like she ordered a variety pack. I've been sitting on my floor for 6 hours straight just watching them. Luna keeps giving me this smug look like 'surprise, you're babysitting now.' The orange one already claimed my favorite hoodie as his bed. Anyone know how long before I can tell if they're boys or girls? And please tell me it gets easier because I'm already emotionally attached to all of them and they're literally potato-sized. Send help (and kitten food recommendations). #Pets #Cats #kittens
