Question about TNR

We have a problem in my neighborhood....the problem is my neighbor feeds the feral cats

I am taking it upon myself to do the TNR (after I gave her plenty of time to do it & offered to help her pay for it), since I found cat poo in my yard the other day & do not want to risk my dogs' health.

Anyway my question is, since she feeds the cats & puts out food, now some neighborhood outdoor pets/cats come around too. What can I do, if anything, to prevent the neighborhood cats from getting trapped?

TIA.

Good luck!!
I would think that if it's a pet, it won't react negatively to you. It might not like you, but it won't try to attack you as a feral cat would.
Or, you could ask around before taking the cat to be fixed, if necessary. Pet cats have probably already been fixed and if not, they need it anyway so you would be doing the owners a service.
