Bird flu is supposed to get here (North America) in a few months which is yet one more reason to keep your cats indoors. Two of the RV parks we lived at previously were fairly near poultry farms. A couple years ago millions of birds in the Fraser Valley had to be put to death. And where we are now there is the duck pond I've mentioned. There are lots of resident ducks (Mallards) and there were migrating Wood Ducks this year. I hope this isn't going to be as bad as predicted.
