Air rifle, you thought it was feral as it didn't have a collar on and it
was a legitimate pest control measure.

That won't stand up in court. Good job too.
It might not.... AFAIK though, shooting feral cats is a pest control
exercise and not illegal. As far as I'm concerned, moggies are all
vermin and any animal that the 'owner' can't control is feral.
