There are several ways to try and keep your cat from climbing onto your neighbour's roof:
- Try to keep your cat indoors as much as possible. Indoor cats can live perfectly happy lives as long they have plenty of toys to keep them entertained. Indoor cats tend to live longer, healthier lives as they are safe from disease and injury due to fighting and road traffic accidents. You may consider installing a cat run which will give your cat safe access to the outdoors and limit him from climbing onto your neighbour's roof. At RSPCA shelters we use catmax enclosures: http://www.catnip.com.au/
- Attach bells to your cat's collar so that he is unsuccessful in predating any birds that may be nesting on you or your neighbour's roof.
- Monitor your cat's behaviour outside and distract or deter them from climbing onto the roof by playing a game with them or spraying them gently with a water pistol. If you are consistent they will eventually learn that the roof is out of bounds.
- Another option is to line the gutters with deterrents such as eucalyptus, lavender or citronella spray or lemon and orange peels as these are unattractive to cats.
