Plague of Pussies

 Of late i have pussy problems , we have a Tom cat haunting us small fluffy and a lovely grey and white specimen, well fed and looked after but someone has forgot to take off his balls . He sings all night and gets a good threshing from our female pair and third cat from next door they have all being sterilised , but my little tortoishell is very nervous so shes pulling out her fur and generally a pissy basket case . Its been a bit of a baffler till the other day i noticed a small cat in next doors bedroom window .  So i figured that must be the female whose drawing the Tom cat , now next door keeps themselves to themselves we speak in passing etc theyve been here years . but animal welfare isnt a strong point she has two dogs something of a Staffie type that she has never walked all the time shes had them , when she had cats before they were always moth eaten and flea covered , i managed to trap one and mange bath it , it had a full coat of fur for months and promptly spent the whole of one winter asleep on our boiler ...The story gets better yesterday i spotted three little cats in the bedroom window watching me garden , im hoping shes just cat sitting but ive a feeling shes planning on breeding them for a bit of extra cash . So it looks as if we will never be rid of Tom Cat , guess its off to order some calming plug ins , has anybody had any success with them ?
