So, you're ready to take your cat safely beyond the great indoors with your "True Adventurer" Cat Harness & Leash set? Fantastic!
Before you buy, make sure you measure your cat so you pick the correct size.
The measurement should be done around your cat's chest.
You want your cat's harness to be snug and fitted so they can't get out of it. When you take the measurement, make sure you're getting close and tight up against your cat -- down past all the floof!
If you have a measuring tape, that works best. If not, you can always do the same thing with string or yarn, and then measure that up against a regular ruler or measuring tape.
If you're between sizes, go for the bigger size if your cat is still growing, or the smaller size if you think they are fully grown.
