The entire point of owning and shooting a catty is you don’t need permission, I,ve shot pigeons and shite hawks in the city centre for years squirrels in the local park an a shit load of ferals on my local train station, just walk public footpaths in the country there are thousands of miles of them heaving with everything you want, I,m 61 years old and have had a catty in my pocket for as long as I can remember, never once had my collar felt
