Hi! I have an 11 yr old cat named Beamer, who has recently been diagnosed with Bone Marrow Cancer. He is being given Prednisone and an iv drip that is supposed to make his bones stronger. My question is, how will I know if he's in pain? His right forearm has the tumor, and his bone is pretty much ravaged, so he is walking around on one bone on that leg. He was limping previously, but not right now. I think there is another tumor behind his ear. How will I know if my cat is suffering? I don't want him to suffer at all. Should I forego the iv drip and Prednisone so he can have a natural death, or keep it going and make him able to walk better for the next few months? I don't know what to do. He's my baby.
