Feline liberation

From Erica de Graaff-Hunter Sir: Roy Liddle et al, should not have this problem with the decimation of the bird population by cats (Thought for the day, 6 March). The fault lies with the owners, and with the RSPCA for not giving out the information. I have two cats, and both wear a Liberator collar, available in pet shops. This collar has a small electronic device which, when the cat leaps to kill its bird, emits a very loud noise and flashes a red light (for night-time, I presume). Since wearing Liberators, neither of my cats has caught a bird, and my garden is full of fat ones, all singing hard and drawing attention to themselves. The cats can have the fun of stalking the birds but not of catching them, which also means that I am not constantly removing sad dead bodies and hoovering up feathers. If all cats wore Liberators — problem solved.

Sir: It is a pity readers bothered to complain about Rod Liddle's column on killing cats. Attention-seeking behaviour of this kind, whether in men or cats, is best ignored. Responding to attention-seeking behaviour simply increases the likelihood of repetition — as I frequently tell my readers.
