Kids Cat Onesies Pyjamas

Kids cat onesie pajamas are usually unisex, so there is no differentiation between male and female. Almost all cat onesie designs suit both girls and boys.

The kids will love these cat onesies because they shout “fun.”

For parents, cat onesie pyjamas have a double bonus, they are fun for the kids and they are practical too. Because onesies are mostly generously sized they should last through a couple of growing spurts.

Parents – expect to gain a couple of brownie points for this decision.

Cat – Kids and Toddler’s Autumn/Winter Jumpsuit

This cat onesie for babies and toddlers is just adorable and definitely huggable. There are sizes for this onesie suit from 0-3 months right up to 24-30 months.

The onesie has an easy zip closure. The end of the zip is protected by fabric to avoid the end of the zipper rubbing on skin.

In my opinion this is a super important feature of zipper closures on any onesie. Often the end of the zipper is near the neck so having a fabric closing protects the skin in that area from rubbing.

The zipper also means that it is easy to change a diaper. The cuffs are elastic, not tight but snug enough not to be loose. Not all sizes have feet. The hat is soft and super cosy and lined for extra warmth. The fabric is polyester and can be machine washed.

Wouldn’t your little cutie love a story about cats, while wearing a snuggly, wuggly cat onesie? These irresistible cat stories are for toddlers and young children.

Cat Onesie Pajama Cosplay Halloween Costume

This onesie is called a Flappy Suit because it has airbags inside that move parts of the costume with normal body movement (nothing the child has to do).

The ears and the tail moves when waring this onesie.

This movement is apparently (because I have not seen this costume) a real surprise for kids.

Just to get an idea of the movement aspect, there is a terrific super quick little video of a little boy moving the ears on his monkey costume. Scroll down down the page into the reviews and it is not far past the photos of kids in the costumes. It will bring a smile to your face.

Onesies like this make great costumes for kids. Onesies are not fussy to put on or wear. Onesies are comfy and it is easy to get into character.

Kids can wear their own clothes underneath the onesie, for example jeans and a long sleeve T shirt.

For kids who are not too sure about wearing a onesie, having their own clothes underneath is a bonus. The onesie can always come off if necessary. A big bonus in my book. The onesie is described as thick, soft and warm. Ready for the chilly weather.
