can animals breath under covers?

i have to animals (1 dog, 1 cat) that love to sleep completely submerged under the covers on our bed. it doesn’t seem like they have even a small air pocket to draw air from. how do they do this? how long can they stay under there before i should be concerned?

thanks in advance!

One of my kitties (Mei Tu Blue Point Siamese 1963- 79) loved sleeping under the covers. Never hurt her.

I have three cats, they all went through they’re under-cover-phase.

Blankets/sheets/towels are breathable. Tiny little holes for air to get in and out. In fact I try to sleep under the covers when its mosquito season, but blankets help keep heat in and it quickly makes it too stuffy for me.

Since cats breath and exhale less air, it won’t become stuffy for them as much. Ummm also i don’t think they release as much heat b/c of fur. They might get really hot tho. Anyway, I’d only be concerned if it was a really heavy thick blanket. Otherwise they’ll be just fine, and eventually get up once they get too hot.

They should only stay under the sheets for 3 hours - no more, no less. After that, and before that, your body heat and the animals’ respiration with convert all oxygen to dingleberries (which collect around your eyes and other bodily regions while you sleep). Oxygen dingleberries cannot penetrate the mucous layer in their alveoli, and you know what that means…

As long as you are not sleeping in a zip loc bag (and even if you are, just make sure that the yellow plus blue don’t equal green), the animals (and you, should you decide to join them) should have plenty of oxygen to make it through the night. If you doubt this, have a friend or family member sit by your bed and you pull the covers over your head. Stay there until you start to get dizzy from lack of oxygen. When you start feeling woozy, say a code word that will alert your assistant that you are in trouble and you need air NOW! If you have to call for help, DO NOT let your animals sleep under your covers. You’ll be asking for tragedy.

Even if your blankets aren’t very breathable, and assuming that your animals have at least one leg each and they haven’t had any serious head trauma, they will seek air on their own if they run out (which probably won’t happen).
