Ok, I am an animal lover, but I am getting really frustrated. My 2 yr old and I recently started a flower garden in our front bed. By the end of the afternoon, next door's cats had descended upon it and turned it into their litter tray. They have destroyed everything we did. These things terrorize my dogs and I can't just go and shoo them as I'm painfully allergic. Ds wants to go and look after his garden but its not safe because of all the cat mess lying around. I need practical advice to keep the cats off so the flowers can grow. I really am at a loss. So tempting to soak them with a water gun but don't want to be cruel!
