Let's go ahead and get something out of the way right from the jump: I am very into dressing my animals up. At any given point, you will find some combination of the following animals in my home: three dogs, one cat, a gecko, and two fish. Sadly, as far as I know, outfits and costumes do not exist for geckos and fish. Happily, as I am familiar with, costumes and outfits do exist for dogs and cats .
I don't know exactly what made me consult the great oracle that is Google to query whether or not pet pajamas exist, but if you've ever wondered the same thing, let me tell you: they do. They do, and they are glorious.
I also don't really know why you would ever put pajamas on your mammalian friends, especially since they have all that fur that is there to keep them happy and cozy, but the human mind is a funny organ and sometimes, you just want what you want.
This one is dedicated to my fellow compatriots in animal dressing: Here are all the pet pajamas I'm obsessed with right now.
Halloween Onesie

Because Halloween is just around the corner, I would be remiss not to kick things off with this cute little onesie that is appropriately themed. If Halloween is your favorite holiday we can go ahead and assume it's your pet's favorite, too, right?
Fleece PJs

Fleece pet pajamas are especially funny to me, but there are definitely situations where it makes sense to give your pet an extra layer. After all, my dog regularly tries to climb straight into my blanket every night, so maybe he could benefit from something like these.

Plaid PJs

HELLO LUMBERJACKS! OK, seriously, I don't know if anyone is actually still a lumberjack in this day and age, but red-and-black plaid is enduringly popular. Now your cat or dog can get in on the fun, too!
Rubber Duckie PJs

OK, so, I threw this one in because it's bright, cute, and it vaguely reminds me of human babies in a way that I'm more or less OK with. Can't you see your favorite furry friend ensconced in this sweet little outfit? Me, too.

Pink Little Lamb PJs

I'm not saying you have to have your own matching pink lamb pajamas if you buy these for your dog, but I'm also not saying that you shouldn't at least strongly consider purchasing some.

Plaid Hoodie PJs

Plaid is back! These might actually be superior pet pajamas because they double as a hoodie, and hoodies are the most comfortable clothing item maybe ever, and … wouldn't it just delight you to see your favorite furry friend tooling around in this ensemble? Say yes.

Elf PJs

Ho ho ho: it's never too early to start thinking about Christmas, right? Sure. You can buy these elf-themed pajamas to match the same ones you buy for your human family, or you can just get them because you like them.

Orange Hoodie

This hoodie isn't exactly filed under pet pajamas but there's reason it can't do double duty. I mean, look at it! Orange is the new … orange! I don't know! It's precious.
