A cat jacket is essentially a vest for your cat, with a D ring on the back for the leash clip. Instead of a zipper or buttons for closing the vest, as you’d find on the human version, you’ll want to use velcro. Velcro allows for slight changes in your cat’s size, and keeps the vest secured around your cat even if they pull on the leash. You can find and download a cat jacket pattern online, or you can make your own. To make your own, you’ll need your cat’s measurements, paper, a pencil, a ruler or measuring tape, and probably an eraser. The cat jacket will be assembled from two parts, but since all the parts are the same size and shape, you’ll only need to draw one pattern.
The paper you use will have to be at least as wide as your cat’s larger circle measurement plus a couple of inches, and as tall as your cat’s length measurement plus a couple of inches. In our example, you’ll need a piece of paper at least 17” wide and 8” tall to be certain the pattern will fit on it. Alternatively, you can use two separate pieces of paper taped together. Since you don’t need any special paper to draw a pattern, you could use a piece of a newspaper, the back of a poster, or something similar. The exact shape and design of the cat jacket can be anything you want, but the important parts to remember is that each section you measured on your cat has to be the same size on the pattern. However, since you’ll need to add velcro to the two circles that go around your cat, you’ll need to make sure these flaps overlap each other so both sides of the velcro will touch. EXPERT ADVICE Pippa Elliott, a licensed veterinarian, makes a point about safety: "Never cut corners and use safety pins as fastenings. Not only can these come undone and hurt the cat, but if swallowed they can cause serious bowel problems."
