It is possible that Bone has bronchitis, bacterial or fungal pneumonia, a parasite, or cancer. Any of those things are possible. Since he seems to have improved on the antibiotics and steroid injection, it might be a good idea to have a recheck for him. Your veterinarian may want to recheck x-rays to compare for any improvement, and may be able to give him further treatment.
Four of the five species of the big cats (the Panthera genus – lion, tiger, leopard, jaguar and snow leopard), the exception being the snow leopard can hybridize with each other to produce numerous hybrids. In fact, breeding of two different pantheras to produce hybrid big cats has been banned in many zoos and animal sanctuaries due to no conservation value of the hybrid, and the risk it poses on the mother that gives birth to it.

Ligers enjoy swimming, which is a characteristic of tigers, and are very sociable like lions. Ligers (and tigons) exist only in captivity because the habitats of the parental species do not overlap in the wild. Historically, when the Asiatic Lion was prolific, the territories of lions and tigers did overlap and there are legends of ligers existing in the wild.
If Chester’s respiratory rate is over 100 breaths per minute you should visit your Veterinarian immediate for an examination since this is well over physiological range; infections, anaemia, allergies, congenital anomalies, foreign objects, fluid, parasites among other causes may be the underlying cause. I cannot give you any at home advice in a case this severe except to visit a Veterinarian for a thorough examination. Regards Dr Callum Turner DVM
If your cat is struggling to breath and is not eating or moving, it could be a sign of trauma in cats. A steep fall, collision or dog attack can result in internal injuries, which can affect your cats lung capacity. An internal hemorrhage, intense pain, fractures or pneumothorax constitute as emergencies that can cause fast, superficial abdominal breathing in cats.
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!
