Instructions
Purchase a collar made specifically for your type and size of pet. Dogs, cats and ferrets have their own sections in most major pet stores. Expandable or breakaway collars are a better choice for cats because they tend to get caught and might choke if their collar is drawn too tight. Very young pets, less than 6 months old, shouldn't be fitted with collars.
Have someone hold your pet still if it tends to resist having its collar put on.
Wrap the open collar around your pet's neck starting at the bottom of its neck and bringing the two ends to the top. This will allow you to see how the buckle works.
Close the collar, leaving a bit of slack. Some collars snap closed like a seat belt or messenger bag. These must be adjusted to fit your pet prior to being secured around its neck. Some collars have a buckle similar to a small belt. This type can be fitted as it is being put on.
Check to make sure your pet's collar isn't too tight. For a very small pet such as a kitten or ferret, try to slip one finger between the collar and your pet's skin. The collar should feel snug, but not tight, with your fingers under it. If it still seems loose, tighten it. If you can't fit your finger under the collar, loosen it. For a cat or dog, use two fingers for this test.
How to Put on a Neck Collar
Neck collars have been used for as long as humans have had domesticated animals to control or identify with tags. In modern society, collars are most frequently used on pet animals, usually dogs, cats and other small mammals, such as ferrets. Designs of collars have become increasingly simple and safe. Proper selection and use of pet collars is essential to the health and safety of your pet.
