Help! My cat has been spraying all over the house. He is 5 years old, neutered at 6 months and I’ve had him since he was 9 months old. He has been marking his territory all over the house for 2 - 3 years and it’s getting worse. We have 5 cats total. They all get along, but he is very territorial. We use a feliaway diffuser and when it’s new it seems to help, but as it runs low the spraying gets so much worse. Is there anything that works better than feliaway or is there a better way to diffuse it such as a focusing collar? Of course he is our favorite cat and we could never get rid of him, but there are days it’s almost too much!!
