Story
Meet Tiny- Tiny is a 1-year-old domestic shorthair who is searching for her forever home. She may come across as a little spicy at first, but that's only because she's scared and unsure of her surroundings. New situations can be overwhelming for her, and she needs someone who understands that trust takes time. With a calm approach, quiet voices, and slow movements, Tiny begins to relax and let her guard down. Tiny would do best in a peaceful home with a patient adopter who is willing to let her set the pace and give her the space she needs to feel safe. Once she starts to warm up, you'll see glimpses of her sweet personality shining through. She isn't a cat who will rush into affection right away, but for the right person, earning her trust will be incredibly rewarding. Because of her sensitive nature, Tiny would thrive in a home that's not very busy, where she can feel secure and stress-free. If you're looking for a quiet companion and have the patience to help a shy cat blossom, Tiny could be the perfect match for you. Does Tiny sound like the match for you? Stop by the Adoption Center during open hours 11am-4pm Thursday-Tuesday (closed Wednesdays). Primary Color: Black Weight: 3.02 Age: 1yrs 0mths 0wks
