We have the spray... It's not 100%... The cat seems most interested with the sliding door that goes out of the bak of the house and I have put an old wood/metal milk box (the kind from the 50s) there and we leave it there...

That's why he is now interested in other doors... I'm going to keep spraying and I'm gonna put some cyannne pepper down around the others and see if that works...
