Meet the tiny bosses: Blueberry & Ziyue.
VIVI & BERRY began with two very different cats: curious Blueberry and plush, big-built Ziyue. Their everyday adventures shape the gear we choose—comfortable, secure and made for real cat moments. Please measure your cat’s chest before ordering.
Measure. Clip. Explore.
Built around breathable mesh and an adjustable vest-style fit, our harness set is selected for confident walks with British Shorthair and chonky cats. Measure the widest part of the chest before ordering.
Fit & Safety FAQ
How do I choose the right size?
Measure the widest part of your cat’s chest: S 23–30 cm, M 28–38 cm, L 36–46 cm. If between sizes, choose the larger size.
Is any harness completely escape-proof?
No. Check the fit before every walk, introduce the harness indoors, and supervise your cat at all times.
What is included?
One adjustable cat harness and one matching walking leash in your selected color and size.
How should I introduce the harness?
Start indoors with short, calm sessions. Reward your cat, check the fit, and only move outdoors when your cat walks comfortably.
When will my order arrive?
For the current harness, allow 1–3 business days for processing plus approximately 5–11 business days for US delivery. Delivery estimates vary by destination and carrier.
