I have a cat thats about 17 and i love him. Though it looks like he is reaching his time. He is blind at this point and lately has have had trouble breathing. He doesnt do much. I dont know if he is suffering or not bc he talk but i suppose he is. Should i take him to the vet and go ahead and let him rest in peace? i would like your opinions bc at this point i dont really know what to do. thanks
