Thank you for your email. I do think that there might be more going on than stress, and kittens are prone to infectious diseases. If you don't trust that veterinarian that you saw, it would be a good idea to find a second opinion, even if you have to travel a bit to do so, as he could have a problem that needs to be treated. You can also call your veterinarian, let them know that he isn't getting better, and see if they have any other recommendations for him.
There are a few possible conditions which may affect a new mother a few weeks after queening which may include eclampsia, infections among other conditions which may lead to difficulty in walking and breathing. Since Noor is still nursing her kittens, you should take her to your Veterinarian for an examination (good to take the kittens too as separation may stress her) and see what they find with an examination and blood test.

The Russian Blue is a robust breed, with firm muscles and an overall dose of good looks. It is physically in the same class as the Korat and Oriental Shorthair -- long, slender, elegant. It is of a medium size, and muscular, but compared to a swimmer in the compactness of its musculature. When it is in full motion and stretched out, one can see that it has a long, graceful neck, but the neck is hidden by thick fur and high set shoulder blades when the cat is sitting, making it look as though it has a short, thick neck.
Blood transfusion for acutely anemic cats or cats who have suffered significant blood loss or kittens who have neonatal isoerythrolysis. Blood typing must be carried out before a blood transfusion. Cats have three blood types, Type A, Type B and Type AB. Type A cats can only receive type A blood, Type B cats can only receive type B blood, and Type AB cats can receive blood from type AB blood or type A blood.
These intelligent animals will require substantial amounts of physical and mental activity. Keep toys lying around the house at all times. When they feel the need to “hunt”, a ball of string or a toy fish should capture their attention for hours. Keep in mind that these types of toys require human supervision as the contents could be chewed up, which can be harmful for your cat’s health.
Sorry to hear your kitty is scratching like that! Does he show any signs of skin infections, fleas, mites, wounds from other cats? The cone could have stressed him further, yes, if he was scratching already because of tension/anxiety. Open sores can get infected, especially when left untreated and scratched further. We would recommend taking your kitty to the vet for a diagnosis. They will be able to provide you the advice and medication your kitty might need. Best wishes!
