Step 1: Measure Your Cat's Neck Size.
This will help you determine the size of e-collar you need and how tight you'll need to make the e-collar.
Step 2: Adjust the Collar to the Correct Size.
Different brands of e-collars secure differently. You might use your cat's regular collar, ribbon or gauze, or snaps to adjust the size and secure the shape.
Step 3: Put the Collar On.
Standing behind your cat, slide the smaller opening end of the e-collar over the cat's face and onto the neck. Adjust the collar accordingly. Gently pull the cat's ears forward. The collar should be snug, but not too tight.
Step 4: Removing the E-collar
Working from behind, loosen the collar. Slowly pull forward over the cat's ears and gently slide off.
