Can I use a Pet Bed Warmer with this product? If so, which size?
This is possible if you use our medium size Pet Bed Warmer, but it needs to be placed under the foam. We recommend adding an additional layer of foam to the bottom so the heater fits in between the two layers.
Do you sell the foam piece that goes under the cover?
While we do not sell replacement foam, you should be able to find something comparable at a local craft store. Simply cut it to fit your Kitty Sill.
Does this product require a certain window sill depth?
The window sill needs to be at least 2" deep.
Do you sell replacement bolster covers?
Unfortunately, we do not offer bolstered replacement covers for the Kitty Sill.
