I am waiting for him to get back. From what I can make out, the neighbours have the cat back inside now and we aren't allowed to knock at doors and ask to see cats. That is why I am hoping he calls back with an update soon.
It is possible the cat is elderly but I would expect the neighbours would have explained it it was genuinely elderly/ill.
The road is literally 1 minute from here but I have no idea what street number. If the cat was out and the man could give me access to the back, I could take a camera and send photos to the RSPCA.
I know at the same time people can exaggerate - eg the "Feral" that had "Lacerated" the woman's arm. When I got there, she had a regular scratch on her arm and I picked the cat up purring and put it in the carrier
All the same, we have to take people at their word. I don't think he would have tried to phone at 5.30am without good reason.
