Hmm...
For the Deaf ferrets, I use a specific Sign Language for each and every action....Something they'll easily learn, nothing complicated or fancy...
I've also fostered Deaf Dalmatians... Same deal with the Sign language { for Sit, I would lower the hand firmly in the air, heel was patting the hand on the ground in front of you *Vibration*, "Treat" was Groping the air near my mouth*after they see u several times doing that while holding treats, they get the point* Discipline was easy, use harness, corrective tugs, "No" was Index finger firmly pointed near the face, not too close with corrective tugs at first, never switch signs, never use same signs for anything else}...
Worse thing to do for either Dog or Ferret ( and yes, Deaf Humans *L*)..Approaching from behind, catching off-guard to grab attention...
in the animals case, you could get bitten or you could upset them{in the humans, an elbow, or slap or punch if they're high strung...}

We have a growing population of Feral cats in Athens county, because immature Students make cute kitty cuddly adoptions, when the Quarters over and they have to return to mom + pop....the City gets the kitteh...
Many locals implore them not to do that..
But, ever since the Cat shelter was closed due to lack of funds and volunteers [ this happened when I first moved in ], the numbers grow..
Some residents even offer advise on those wanting to help control the Feral population, by setting Humaine traps, and Neutering / Spaying...
Taco Bell on the main downtown road has a pack of feral cats called "the taco bell kitties"
The running joke is a little...dumb...and racist...{ there's a chinese buffet across the street...}
