Calvin is a rescue that I adopted from a foster who had 31 cats and kittens. He was having seizures and appeared to have difficulty hearing and seeing. I brought him home to his 8 brothers and sisters and my wife and I watched him closely. He has been with us for nearly a month and has had no sign of siezure activity. In addition, he seems to respond to sound (his name) and chases the red dot. It is truly a blessing to have this sweet little angel in our family.
