Yea, my deer are constantly violating the 3 feet rule and attempt to get in my face presenting a covid transmission risk, especially when we are indoors.
As has been pointed out animals carry all sorts of disease and viruses and have since time began, this is nothing new or of a huge concern. Just more Fear Mongering.
I have a few that come onto my front porch looking for cat food to eat.
If you sit calmly on the porch steps early in the morning a few of them will come up to you and this one will lick your hand... maybe that’s a bad idea...
They scare the crap out of my poor cat..
I came upon a UPS truck as I was driving into my place on my long driveway.. the driver got out and said he was going to leave my package on the porch but there was a deer on it...lol
