I know this may sound like a stupid question, but i am at my wits end here. my cats want to pee on them...and it smells up the house not to mention taking the paint off the heaters. please please help me....is there something i can buy or do, to protect the heater so they cant reach it, maybe something i could fit over it that is safe but not allowing the cat to get close to it to pee on it.please dont laugh....it is awful waking in the middle of the night with this stench going thru your nostrils.waiting and hoping for some miracle answer from you...thanks
