Days went by and nothing much happened.
I tried to get rid the boredom but ended up sitting in the room.
I played with the cat when the other cats ran away or asleep, glad to have someone to engage with, even if that someone is the cat.
Gradually, the cat became less outraged and I allowed it into other parts of the room.
The cat occasionally let herself be petted.
I'm delighted with the mother cat's progress and looking forward to have more kittens soon and it will be a 'total kitten happiness' in the near future.
I just can't wait for that day.
