I found that Ikea sells little wooden doll beds for $19.99 that are the perfect size for a cat, small dog or bunny bed. The beds even come with their own linens! After reading this article: Ikea Doll Cat Beds, I went and bought three of these beds and decided to try them out with my cats.
This is the bed, and you can see Ikea now offers them at a “new lower price” of $14.99, which is pawsome!! Ikea Doll bed listing
