Advice needed cat with some kind of immune system problem

[Sadless]

My cat is about 16 months old I got him about 4 months old since then he's had different problems. Eye infection gums bleeding and infections then developed lumps in his neck. He was tested for feline infection leukemia each time he's had treatment. He had his teeth cleaned and some sealant put on. The first test came back negative second a slight mark around positive and then today slight positive. Vet isn't convinced it's leukemia and says he might have a immune system problem. This morning he been panting and has blood coming from the gums again.
He's in vets now having oxygen blowed in cage had routine bloods a blood smear and the leukemia test again. Any advice on what it might be.

Thanks

No advice or ideas, but how's he doing at the minute?

I took him back to the vets on Friday morning and the vet gave him another steriod injection and said he's got a autoimmune disease his blood isn't clotting at all. This morning I moved him and he yelped and didn't look at all
I took him straight to the vets and he said its as bad as it can get and I had to have him put to sleep. I am heartbroken he was 16 months old and he was like my shadow and now he's gone.

Thanks for asking

I am so sorry to hear about your wee cat. They really become part of the family 😔 my daughter has 3 and was distraught when they went to get neutered. Xx

That's Harry 2 weeks ago

What a beautiful boy he was. I'm so sorry to hear this ❤️

He was so handsome, I’m so sorry for your loss

Thanks for the replies.
He made my life better in the last year he was such a good cat I will miss him terribly. I took him to a pet cemetery place and will have him home tomorrow night hopefully.

So sorry. He was beautiful.

So sorry for your loss. He was so young, it's utterly heartbreaking. But for the short time you had him, he knew you loved him. Take care xx

Ohhhhh. What a beautiful cat. I have a weakness for tabbies. I’m so sorry about Harry x

I am finding this really hard I have lost cats before but this cat was like my baby and I still can't believe he's gone. I have lost my friend he was there for me. It really is losing a family member I expect to see him everywhere and he's not there. I know time will heal but I don't want to forget about him. He really was a amazing cat to me he really did touch my heart.
Thanks for the replies
