Story
Hello, I'm Patsy, a sweet senior cat who loves nothing more than a good cuddle. My days are best spent lounging around and sharing gentle moments with my sister, Wendy. We've always been together, and we comfort each other with purrs and naps. I'm friendly and mellow, making me a perfect companion for someone who enjoys peaceful days. If you're looking for a pair of loving felines to fill your home with warmth, Wendy and I would love to be part of your family. Adopt us for double the love and purrs!

Story
Hi, I'm Wendy, a sweet senior cat who loves cuddling and playing with my toys. I'm quite mellow and gentle, but I also have a playful side that comes out, especially when I'm with my littermate and bonded pair, Patsy. I can be a bit shy at first, but once I warm up, I'm the friendliest companion. Adopting us means getting two loving friends who will cherish every moment with you. Let's make beautiful memories together! Primary Color: Brown Tabby Weight: 3.4 Age: 12yrs 0mths 2wks
