Wow my cat also had two swollen tumors on each side of him. All the symptoms you state is what's going on with him. I am a firm believer in Silver. I went to the vet today and they gave him a horrible diagnosis and like you said can't do anything. I have started him on colloidal silver 3 times a day for a week and will give him the weekend to try and recoup from the reaction of being lethargic. Send me the best of wishes. Thank you a lot. This brings a lot of hope to me!.!.!
