Just seen your posting, There is a 3 legged cat called Stumpy that has taken up residence at Cator Cars on Bunwell Rd. he is well fed regardless of his claims
He is very friendly but, because he lost his leg in an RTA he is scared of cars & other loud noises.
The distance from Cator Cars on Bunwell Road to Chapel Road by the railway line is a long way to roam on just 3 legs. Perhaps there are two 3 legged cats in the area?
