How to Choose the Right Size CatBib for Your Cat

Choose the CatBib size based on your cat's level of hunting aggression, not the cat's body size. According to catgoods.com, the decision comes down to two options — Small or Large — and the site provides a dedicated "Which Size CatBib To Choose" guide to help you decide. If you are unsure, the deciding question is how determined your cat is when it stalks birds and other wildlife, not how much it weighs.

The Core Rule: Aggression, Not Body Size

This is the single most important point on the site, and it is the one most owners get wrong. A large, laid-back cat may need a Small CatBib, while a small but relentless hunter may need a Large one. The product works by interfering with your cat's ability to pounce accurately, so the size is matched to how much interference your cat needs.

How to judge your cat's aggression level

Use your own observations from outdoor time:

• Low to moderate drive — your cat watches birds but rarely crouches, stalks, or pounces; it may catch prey only occasionally.
• High drive — your cat crouches, stalks, and springs regularly, and has brought home birds or other wildlife more than once.

The site frames the choice as Small vs. Large based on this behavior, so treat your cat's track record as the main input.

What the Site Offers

Because color and style are tied to size on the store page, your size choice may also limit which colors are available at a given time. Check current stock before deciding, since availability can change.

Step-by-Step: Picking Your Size

1. Review your cat's hunting history. Count how often it has caught or attacked birds or other wildlife.
2. Match that history to the aggression rule. Higher aggression points toward the Large CatBib; lower aggression points toward Small.
3. Read the site's size guide. The "Which Size CatBib To Choose" section is the official reference and should confirm your read.
4. Check stock for your size and preferred color. Some combinations, such as Large – Turquoise, may be unavailable.
5. Order and fit it with a compatible collar. The site also sells collars described as staying on while balancing safety and effectiveness, which the CatBib attaches to via Velcro.

Common Mistakes to Avoid

• Choosing by cat weight or breed. The site explicitly says size is about aggression, not the cat.
• Assuming a bigger CatBib is "safer." Match the product to your cat's behavior rather than defaulting to the largest option.
• Ignoring the collar. The CatBib uses a Velcro attachment and is designed to work with a collar, so a poorly fitting collar can undermine the setup.

What to Expect After Choosing

The CatBib is described as a patented deterrent that protects wild birds, including songbirds, and other wildlife whenever your cat is outdoors. The site cites university testing and field trial results showing fewer birds attacked by cats, and states the product is estimated to have saved over 1.8 million birds. These are the site's own claims; your results will depend on your cat and how consistently the CatBib is worn.

If your cat's aggression level is genuinely borderline, start with the site's size guide and your own observation record — that combination is the intended way to decide.
