Cat deterrent advice

[BossHogg]

Our old moggy is making a right mess of our new PVC window sill/frames on the front. Is there anything on the market that we can spray on the window sill to deter him from lying there. Plus its for his own safety as passing dogs have nearly had him a couple of times!

You could try citrus smelling Flash? (Other cleaning materials are available!)

Those plastic bird deterant spikes... Bit OTT but will work.

A dog on the other side of the window?

You do have to keep re-applying (like any of the chemical deterrents), but I've found these work OK:
