Why bother the cat at all? For the number of reasons I have already mentioned!
1. It’s her property, if she doesn’t want it there she can get rid of it at her discretion.
2. Cats spread flees.
3. Cats poop in your yard. Maybe she had a dog like we do that she didn’t want eating cat poop.
3a. Cat poop spreads disease and parasites.
3b. Cat poop dog breath is beyond disgusting.
4. People have a responsibility to keep their pets on their own property.
That is just an anti-cat rant, try to stay on this thread topic.
