Hi, do you guys have any recommendations for a "cat tent"? Let me clarify in the desc.

When it's cold out, my cat sleeps with me under the covers, or I should say, she would if the blankets wasn't annoying her. I don't know if it's the weight of the blanket, the static electricity the blanket causes on her fur or the just the blanket ruffling her fur that bothers her... but I usually hold my arm up to make like a kinda tipi/tent or something for her so she can sleep under my covers with me undisturbed, however after some time my arm gets tired and I also need to fall asleep at some point and I lower my arm. Within a minute or so the blanket coming in contact with my cat starts annoying her and she leaves to sleep on the edge of my bed or next to me. So I was just wondering if there was some kind of small structure on tent that I can put under the covers next to me to make a comfortable sleeping spot for me and my cat.
