JMHO....but as your vet tech friend said...I would not worry.
How wonderful to allow all the kitties to reside with you and the family. Great that you spay/neuter and vaccinate. I know so many farmers around here that do not do either and then are upset they have a million cats running around.
If it's hungry, it finds it's way here. If it's lost or hurt, it finds it's way here.
I am in the process of setting up a TNR for a local farmer who's cat population is just way out of control
Sorry to hear about your dogs....coons sure do keep a distance with those around. There are some great dogs awaiting adoption thru different rescue groups here in
WI, if you ever think of getting another one.
