One of the other problems with cats is that they are competing with native =
animals for food. So yes, there are other things that prey on birds, but th=
ey don't have a home to go to where they can get food=85

At least we had someone at the talk in Wolfville and in Kings County roamin=
g cats are treated exactly life roaming dogs. You can call to complain and =
have them trapped. That raises another issue that Helene brought up. It use=
d to be considered OK for people to let dogs run free. You den't see that a=
ny more because people have realised it is not a good idea.

And no doubt Patrick, raptors on roosts, fox and other
native predators wouldn't kill birds!
Is that what you saying?
The cure would be worse than the decease!
Enjoy the winter

As Helene point out in her presentation to the Blomidon naturalist Society,=
 barn cats can easily be replaced by raptors (given a few places to perch) =

Nick - that's what barn cats are for - keeping populations
of rodents and flying rodents under control. Pigeons, starlings
sparrows - the English kind are all rodents.
The cats help keep a barn clean and do their best
work at night when its dark!
Imagion telling a farmer to lock up his cats at night - near as bad

yes Darrell, they have an impact. My point is that this factor is overblown=

We won't get anywhere legislating that cats be not allowed out but increasi=
