I purchased this heated window sill a few months ago .. to date definitely one of my best kitty investments... it is absolutely Elvira's favorite place to bird watch and take her naps .. she loves the warmth .. without a doubt .. I would recommend this product... I must note.. I did not use the two sided tape to install.. I chose to screw the base into my window sill .. just because my 12 lb girl loves to jump on things like a trampoline and I wanted it more secure ... Elvira425. Pennsylvania. Mon Jan 19 2026
