Two retro reindeer designs in our cat christmas sweater range

This is a small, focused collection. You get the same retro reindeer pattern in two colors: the Cats' Red Retro Reindeer Christmas Sweater and the Cats' Green Retro Reindeer Christmas Sweater. Red leans into the traditional Christmas-card look, while green sits a little softer against most cats' fur, but the knit, the reindeer motif and the fit are identical between them. Pick whichever suits your cat's coloring or, if you have more than one cat, mix and match across the two so the whole household reads as a set.

Both designs follow the same idea our shoppers like: mix and match with your pet. If a family member is wearing one of our human reindeer sweaters, the cat version lets your cat wear the matching pattern for the photo. It's a simple, low-effort way to pull a coordinated Christmas look together without buying a whole new outfit for everyone.

Fit and feel of a cat christmas sweater

Each cat christmas sweater is made from 100% acrylic, which is why they feel super soft and comfy and stay light on a small frame. Acrylic holds the knitted reindeer pattern well and doesn't carry the weight a heavier wool sweater would, so your cat isn't dragging around extra bulk. The cut follows a cat's proportions, shorter in the body and shaped through the chest and shoulders, so it sits closer to how a cat actually moves than a scaled-down dog sweater would.

Cats are particular about anything on their body, so the goal is a piece that feels like a second skin rather than a costume. A soft acrylic knit that lies flat and moves with them is far easier for a cat to accept than something stiff or bulky. That softness is the single biggest reason a hesitant cat will tolerate, and sometimes genuinely settle into, wearing one.

Getting the size right

The most important measurements are your cat's chest girth, taken around the widest part just behind the front legs, the neck circumference, and the back length from the base of the neck to the base of the tail. Measure with a soft tape over the fur without pulling it tight, then compare against the size guide on each product page before you choose. A sweater that fits well sits snug but never tight: you should be able to slip two fingers under the neckline, and the hem should stop before the back legs so it never interferes with the litter tray. When a cat is between sizes, the larger one is usually the calmer choice.

Helping your cat enjoy wearing it

Start with short, relaxed sessions and plenty of calm. Let your cat sniff the sweater first, put it on for a few minutes paired with a treat or a meal, then build up from there. Most cats freeze the first time and walk normally once they realize they can still move freely, which is exactly why the soft, lightweight knit matters. Keep early sessions supervised and indoors, and take the sweater off if your cat seems genuinely distressed rather than just surprised. You'll find more detail on sizing and first-time wear in the FAQ below.

Caring for your cat christmas sweater

Care is straightforward and worth getting right so the knit lasts season after season. Machine wash gently at a maximum of 30 degrees, wash with similar colors, and dry flat. Don't tumble dry, iron, bleach or dry clean any of these sweaters. Drying flat keeps the shape true so it still fits your cat's body next December, and the gentle wash protects the soft acrylic that makes them comfortable in the first place.

The Christmas-card moment

The reason most people buy a cat christmas sweater isn't the cat, it's the photo. Slip the reindeer knit on, get everyone in frame, and your cat is suddenly part of the family Christmas card instead of watching from the windowsill. If your household also has a dog, you can dress them to match from our wider pet range and our dog christmas sweater options, so the whole crew coordinates for the shot. However you style it, the two retro reindeer designs are here to put your cat in the picture this holiday season.
