Taming an adult feral cat can happen. I, and several people I know, have done so. But it is a difficult process, and in every case I know of has taken months. Feral kittens are a much easier proposition. Letting the cat slowly adapt to your presence and come to associate you with food, warmth and companionship until it joins you by choice seems to be the best method, so not something that the team could easily do.
And you are also correct about even a domestic animal biting you when it is injured and confused. I remember getting our loved and long domesticated dog out from under the car that had run over her, and getting bitten in the process. She would never have done that if not crazed with fear and pain, poor thing.
Róisín, you are so correct here!!
Sometimes the best you can hope for is that your ferals will share the same room with you. 7 years ago we wanted to adopt 2 kitties to replace the oldest 2 we needed to put to sleep. (They were 20 and 19. One developed cancer and the other was in pain.)
One of the local shelters was having an adoption day at one of the big box pet stores, so we decided Let's see what they have.
We had other cats still in the household, so we usually opt for kittens, as they assimilate to the household easier.
We found a pair that were about 4-5 months old. They let us hold them and so we filled out the paperwork and once it was processed, we paid the money and took them home. The day we went to pick them up, they told us that they were a still little feral.
They were not a little feral, they were mostly feral. The only reason we think that they let us hold them, was the noise at the adoption event overwhelmed them and they just became rag dolls.
They hid. Cats can hide very effectively. They were in a room, but all the places we searched, we could not find them.
We let them out and we did not see them. We knew they were around. They ate the food and they used the boxes.
We were like UGH!, now what. We kept them, because we knew no one would want to adopt a feral cat, and we did not want them to spend their lives in a shelter.
It took years for us. One now will sleep with us, and crawl on me for scritches and cuddles, but only if i am in the bed. Once I am up, he will spend the day near me, but no touchie! The other still is extremely skittish. She is our hunter. We have an old field-stone house, so mice, chipmunks, voles do get in. (I do patch the holes up every spring, but the critters do dig...)
She now will sit near me and once in a while i can pet her. She is our invisible cat. Though se absolutely adores our oldest male cat. She will chirp at him rub all over him.
They are still petrified of the vet, and we have to give them drugs because they bit the vet. The vet won't see them unless they are drugged. We have been lucky, we have gotten scratched when thy get scared, but usually things are peaceful.
This is what we got, so we are happy with any advancement we get. It is a slow process. The one sat on my spouse's lap the other day while watching TV. Whoa!!
