Without an examination and possibly a blood test, it is difficult to say what the cause for Buddy’s symptoms are; however eclampsia is a possible cause and would require immediate attention from a Veterinarian if this is the case. I am not sure about veterinary care in Jordan but I know that there is a veterinary school in Al Ramtha, Irbid, Jordan if that is close to you if you require veterinary care. https://wagwalking.com/cat/condition/eclampsia- www.just.edu.jo/FacultiesandDepartments/FacultyOfVeterinaryMedicine/Pages/Default.aspx
An increase in respiratory rate may be an indicator of pain especially if she is limping; without examining Isabella I cannot say whether this is due to pain or another cause (infection, heart disease etc…). I would restrict Isabella’s movements and monitor her for the time being but if it continues or the respiratory rate is above 40 breaths per minute you should visit your Veterinarian for an examination.

Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow.  It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
^ "Colorpoint Longhair" has multiple meanings and "Javanese" has been used for at least one other breed; the WCF uses the "Javanese" name for the Oriental Longhair (not colorpointed). The WCF has also merged the colorpointed Javanese/Colorpoint Longhair, the Himalayan and the Colourpoint Shorthair of other registries into a single breed, the Colourpoint. In the CFA, the TICA and some other registries, the Javanese/Colorpoint Longhair has merged back into the Balinese as a division
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.
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!
