Very friendly tortie that appears in my sisters garden on a daily basis. In the past 3 years she's been pregnant more times than we can count, currently she's just a bag of bones. She seems to be being used to breed kittens and hastily chucked back outside once she's done so. Suspected owner has been heard shouting/swearing at her. Now I'm certainly not one to 'steal' someone's cat, but I'm concerned at just how many litters she's had, and how neglected she currently looks. Wwyd in this situation?
