Arghhhhhh! Its driving me insane! She is spayed, about 18 months old, we have 2 older relaxed cats and everything has been fine for a year. But recently she has been spraying in the house, mainly on the toaster (we've chucked one out) and the microwave (on the verge of being chucked too). I have the feline spray to try eliminate the odour but she keeps going back. Help!
