Do your cat(s) and dog(s) sleep snuggled up together?

one time my 4 year old pug and my 19 year old cat slept next to each other on my mom's lap

sometimes but not usually

They did, but our cat was very, very tolerant of other animals.
We were always catching her and K.C all snuggled up and nesting in our blankets. xD
It was adorable, especially because the cat was just a bit bigger than the dog.

Hah, yeah, my cat likes to try and snuggle up with the dog. He's a fat little furball and the dog is a large Lab/Collie mix, and the cat definitely pushes around that dog. Sometimes Loki (dog) will allow fatboy Cas (cat) to curl up with him, lick his head or ears, or roll all over his head, but most times the dog runs away. But I think the cat does this on purpose so he can get Loki off the dog bed and then he can have it all to himself (because once the dog leaves, that fatboy stretches out right in the middle of the dog bed haha).

Sometimes if he comes up to my room

I only have one now, but when I had two they would only snuggle up if it was very chilly in the house. I think it was more of a keeping warm thing than an affection thing.

Our bed is pet free finally, our fat gray cat has decided the couch is a much better place to spend the night.

No. They really don't get along.

I have two cats and when it's really cold outside they like to cuddle each other and keep each other warm. It's so cute!

My cats and dogs sleep together on the back of my big comfy chair, usually spooning. It's a pretty cute sight.
