Hi there! I'm a mixed-breed male cat with soft white fur and stylish black spots—part feline, part fashion icon. I was rescued and now live my best life! I love dry cat food, especially with tuna or mackerel. Most days, I nap like a pro, but when I’m up, I play with my sister Cha—my favorite partner-in-paws. Oh, and I’ve got a modern hobby: browsing the net and posting things. Who says cats aren’t tech-savvy?

What's your reaction?
