very sick kitten, probably FELV

I've got this very sick kitten I'm taking care of, roughly 1.5 months of age, won't gain weight like her brothers, very bloated belly, ill digestion, persistent diarrhea after vermifugation and antibiotics. The doctor thinks she's a case of FELV but she's too small to be pricked with a needle and draw blood for the test.

What would you suggest rather then euthanasia? I'm feeling devastated to even consider it.

Thankyou in advance, folks.

I'm so sorry. I'm new so I don't know what to tell you except maybe a warm CDS bath with a soft cloth. eye droppers, nipples on baby bottle, to help get MMS inside her. I bless you and her. Your intention means so much. Stay calm an give her the unconditional love heals all. Much love to you both.

If you have Jim Humble's latest book, he has a 16 page section on animals. 

Since the cat is so small, be careful not to give her too much CLO2 in whatever form you might use, MMS1, CDS or CDH. 

You could add one drop of unactivated MMS to her drinking water in a plastic dish.
