Story

Fluffy is an amazing pet and we are so sad to need to rehome her. Over the last 6 months she has become aggressive with our other cat. Our other cat has special needs and we are guessing this has something to do with it, though they were besties for a year before this change. We have tried just about everything we can think of but just can’t have our other cat getting attacked all the time. She is great with our young kids! She’s incredibly cuddly and very sweet with people. She, like most cats, gets shy when new people visit, but she warms up to others quickly. We’d love to find a home with her where she’ll be cuddled and loved without the stress of kitty fights!

Story

We are looking for a nice home for our sweet boy Ziggy. We have loved him for ten years, and find this decision difficult. We are rehoming at no fault of his own, our toddler has developed severe allergies to him. Ziggy loves to cuddle and be close to you. He gets along with dogs very well! He has no medical issues and stays fat and healthy on air 😅 if you're looking for a gentle snuggle buddy, Ziggy is the boy for you.
