Horror film with psycho cats

I saw this in the 80s, but it was made in late 60s/early 70s. Fairly sure it was British.

Plot: Adult man returns to live with his mother. Mother has a cat. Man thinks cat is out to get him. Man gets rid of cat, mother gets another one. Different cat, same behaviour. Rinse and repeat. Things escalate, think mother passes away, cat kills man.

Could have been an episode from an anthology series but think it was a short(ish) film.

1975, somewhere in France

This was taken in Brittany or Normandy, I think. Any ideas, please? I’m trying to locate the campsite we stayed at so knowing this town would help narrow down my search area. (Campsite was inland, definitely not coastal, in the grounds of a chateau, and had its own lake.)
