Step-by-Step

How to Measure & Fit
Your Cat's Collar

Every Kiokatt collar has a breakaway safety cat buckle designed to release under pressure if your cat gets caught. Here's how to get the perfect fit.

Measuring a cat's neck with a soft tape measure

Measure the neck

Wrap a soft tape measure around your cat's neck where a collar naturally sits. Pick the size whose range includes that number plus about 1 inch.

Pressing both sides of the breakaway buckle to open it

Open the buckle

Press both sides of the buckle to open it. Always unbuckle first. Never pull a collar over your cat's head.

Fastening the collar and sliding the adjuster

Fasten & adjust

Clip the buckle closed around the neck, then slide the adjuster until snug. Turn the collar so the D-ring (where charms hang) sits under the chin.

Sliding two fingers under the collar to check the fit

The two-finger test

Two fingers should slide under the collar snugly. Can't fit two? Loosen it. Fits three or more, or slips over the ears? Tighten it.

How to open and close a breakaway buckle for your cat

Watch how both sides of the buckle press to open, then click back together to close. This video has no sound.

First Week With a New Collar

  • Start with short sessions (10–15 minutes) paired with treats or play.
  • Scratching at it or walking funny at first is normal. Most cats adjust within a few days.
  • Stay close by until your cat is used to wearing it.
  • Re-check the fit after the first day. Collars can loosen as the fabric settles.

About the Breakaway Buckle

  • The buckle is designed to pop open if your cat gets snagged, which helps prevent choking or injury.
  • Never clip a leash to a breakaway collar, since it's made to come apart. Use a harness for walks.
  • Check the fit weekly for kittens (they grow fast!) and monthly for adult cats.
Step-by-Step

How to Put On a
Step-In Cat Harness

Our step-in vest style goes on without pulling anything over your cat's head. Follow these 4 steps for a safe, snug fit.

Lay flat, mesh up

Place the harness flat on the floor with the soft mesh side facing up.

Step paws in

Gently place your cat's front paws into the two leg openings, then lift the harness up and around the chest.

Fasten & clip

Close all the fasteners along the back. Clip the leash through both D-rings for a balanced, secure hold.

Check the fit

Two fingers should slide under the harness. If you can't fit two fingers, go up a size. If it shifts or your cat can back out, go down a size.

Pro Tips for First-Timers

  • Let your cat sniff and explore the harness on the floor before putting it on. It really helps reduce stress.
  • Do a few 10-minute indoor sessions before any outdoor adventure.
  • If your cat freezes or flops over, that's normal! Offer a treat and keep sessions short and positive.
  • Never leave your cat unsupervised in a harness. Take it off after every walk.
Sizing Guide

How to Measure
Your Cat

Find the perfect fit every time.

Collar Sizing

Measure where the neck meets the shoulders, where a collar naturally sits.

  1. Wrap a soft tape measure around the base of the neck.
  2. Note the measurement in inches.
  3. Choose the size whose range covers that number plus about 1 inch.
  4. Most adult cats measure 8–12 inches.

Harness Sizing

You'll need two measurements: the neck and the chest (the widest part, just behind the front legs).

  1. Neck: measure at the base, same as for a collar.
  2. Chest: wrap the tape just behind the front legs.
  3. Chest matters most. If you're between sizes, size down for escape artists or up for bigger cats.

Clothing & Hoodie Sizing

Clothing fits best with chest, back length, and neck measurements. Back length matters most for shirts and hoodies.

  1. Back length: base of neck to base of tail.
  2. Chest: same as the harness measurement.
  3. If you're between sizes, size up so your cat has room to move.

Exact measurements are listed on each product page. Still unsure? Message us with your cat's measurements and we'll help you pick.

Care & Washing

How to Wash & Store
Your Cat's Gear

Keep it cute, keep it clean.

Collars & Harnesses

Spot clean light dirt with a damp cloth. For a deeper clean, hand wash in cold water with mild soap and lay flat to air dry. Don't machine wash or tumble dry.

Clothing & Hoodies

Hand wash, or machine wash on a gentle cycle inside a mesh laundry bag. Use cold water only, then lay flat or line dry. Don't iron over printed designs.

Charms & Hardware

Wipe charms and D-rings with a dry cloth. Don't let them soak, since that can cause tarnish. Dry right away after they get wet.

Storage

Store items clean and dry, away from direct sunlight, to keep colors bright. Check buckles and stitching for wear before each use.
