The Gatsby harness comes in three sizes (small, medium & large), and each one has a large range of adjustability on both the front and back straps.
The range is designed so that from the youngest of kittens to the largest of cats, there will be a Gatsby harness that is the perfect size for them.
Just visit our harness size & measuring guide to find your cat's perfect size!
Will one harness size fit my cat all the way through their growth?
There is a LOT of adjustability in all of our harness sizes, so there is a very good chance that you will be able to use a single size and adjust it as your cat grows. Obviously this depends on your particular cat and how much growing they will do - but as an example, one of the models on our store, Lola - still wears the 'small' size Gatsby harness that she first wore as a kitten, even though she is now 4 years old and fully grown.
