Negative Positive
Title: Works only for 1 year : (
Review: I purchased 3 of these for my barn cats (2 small and 1 medium). They worked for one year. Now they overheat and are curling up at the ends, rendering them dangerous and useless. I am thankful we checked them soon after plugging them in this year or the barn would have burned down. So disappointed, now need to find a replacement and am annoyed that I wasted money.
Is the review positive or negative?
