in order not to hijack another members post, and since i do not know enough about cat stoves, will you please post your experiences with how long your cat stove has lasted?? how frequent, if ever, has your cat been changed? i'm the owner or a pre epa non U.L. listed stove (yes, insured too) and by the sounds of the postings, i'm glad i didn't get a cat stove....change my mind and i'll help cook at the hearth.com summer picnic!!
