My cats are the best part of my life. Just adopting my cat Dora in February gave me more of a reason to be better to myself than I'd been recently. It's amazing getting to take care of my little one and have her depends on me, even if she's an anxious little thing that sheds too much and is allergic to normal cat food... I adopted Rowena in June/July and she's about 5 months old now and a major hassle but when she's sweet (aka sleeping), it's so perfect.
I feel like cats are pretty independent by nature and I could never take care of a dog. Just having to take them out every 4 hours seems like a major hassle when I spend 12 hours away from home everyday. The cats poop in a box and give me lovens and cuddle with me to watch Netflix. They don't slobber or bark or do weird dog things. Cats are basically perfect.
