I would as well, but it's illegal to own and use one in town these days unfortunately.
If it weren't I'd be doing something about those 'feathered rats' as well as the stray cats.
But my spray worked well about 1.30am this morning, score now stands at Sprays-2, Tomcats- full bladders.

@Triphid the major advantage of an airgun is that it makes less noise than a door banging shut and just hitting near the cat is enough to discourage them

@Cyklone Oh yeah had a nice one back in the 70's, a German made one with a cylinder to hold air compressed by pumping a lever under the stock.
You could regulate the pressure used for each shot, maximum pressure could send the .177 LEAD slug through a corrugated iron water tank with ease.
It cost me $80.00 and I think the brand was either Erma or Irma.
No breaking it at breach either, a kind of bolt action instead.

@Triphid Nice. Mine uses a compressed air cylinder I fill from a dive tank.

@Triphid nice
