Great fred, Piranha in our canals ans santa thinks mink are feline

GL stewarts rise.

Feral cats are an issue, many semi rural non ferals roam much further than people think,

Mink population been severely depleted by Otters (apparently), the Otter population is off the scale in a relatively short period.
Even in urban areas.

Beaver the talking point atm, been released all over UK, they remove a lot of trees, especially mature hardwoods they don't like,they use that for building, it's  thar way of clearing space for prefered edibles like  willow,aspen, poplar.
On rivers they don't really build dams but burrow into banks causing collapse, which some ain't happy about.

beaver or lack of it is always a problem

I'd dispute the cat roaming tbh, plenty on my street and none venture 50 yards from home, ever.
I have one visitor from further up the village, maybe 150 yards, but he is an exception

Tried to get away but got collared.

swans n ducks etc etc get wiped out...not so sure about beavers
nr ware i live but heard they beeen re intoduced tho

minks and otters n....

but we av the carnforth piranah, in the canal

crocodiles, perhaps?

You can have Beaver on your doorstep Foyles and never see any

Saddo, Cats are natural predetors and love to hunt the woods and hedgerows at night. My mate has one, disappears for days and be seen over quarter of a  mile  away in the woods, sometimes comes home filthy, injured or  covered in ticks.

It's rare though, 8 on my street including my 2, and I could find any of em at any given time of day,
all of em sleep indoors.
