    Hi all, I'm new here, lovely to meet you.
    I desperately need your advise and suggestions regarding my cats condition. Temperature, lethargy, weakness, loss of appetite. Blood tests came back signicating liver issue and especially kidney failure. Ceratinin (2.1) in urine and high billirubin (2.2)
    They keep guessing, after 3 days of a hospital stay (antinflamatory, different antibiotics, hydration) we are still waiting for lab tests to confirm mycroplasma. They gave Rusty a course of Ronaxan antibiotic, 50mg per day. My worry is that is the medication book it says it should not be given to young cats (Rusty is 2) or those with liver and kidney problems. What to do? Is there another antibiotic that can be used in this case, pls advise? Thank you in advance.

    One of my cats was diagnosed with mycoplasma when he was being tested for everything trying to identify the cause of his noisy breathing. My vet said we needed all those tests done before seeing a specialist since they would require any issues dealt with before any consult. Mycoplasma was the only condition identified. My vet said my boy was probably asymptomatic but he gave my boy 3 weeks of Ronaxan anyway. (He actually had 6 weeks in the end but it made no difference.) The trouble is that so many cats are carriers and even treating will not guarantee getting rid of it.

    There is another form of mycoplasma which used to be called haemobartonella felis. If your cat is suspected of having this disease it can be very serious indeed but I think it causes severe anaemia which presumably would have shown up in his blood tests.

    Ronaxan is a form of tetracycline which can interfere with the formation of teeth in young humans and presumably young cats as well so that might be why it is not recommended for the young. It might be worth looking at the datasheet.

    You could also look at Langford's explanation of mycoplasma.

    I think far too much attention is paid to the possibility of tooth discolouration, especially since the form of Tetracyclin in Ronaxan is less likely to cause this than the more ordinary form. I had to give it to some kittens and their teeth look fine.

    A much bigger problem in my view is that Ronaxan tablets MUST be followed up with a syringe of water as they can cause serious damage if they lodge in the oesophagus. There is a liquid doxycycline available in Australia (for export only!) which avoids that problem, plus it allows much more accurate dosing. However AFAIK vets here cannot prescribe it.

    Biscuit had his Ronaxan crushed in treat food. My vet said that was fine.

    Do you have any knowledge of cat should be taking it if kidneys and liver are weak? Rusty is supposed to take 50mg of Ronaxan once a day. He felt sick after first time we have it to him, vomitted the next morning.

    You need to talk to your vet about this.

    @OrientalSlave - I have had the tablets of Ronaxan for one of my cats who has respiratory flare-up episodes, and also had the liquid Doxycycline for him at different times, without any problem.

    I was told by a new vet (incorrectly, as it turned out) that Ronaxan tablets could not be crushed, so I couldn't hide them in food. So I asked for the liquid Doxycycline which had to be ordered. It has to be reconstituted with sterile water before use. It was pretty expensive (about £36 a bottle as I recall, but there is far more than needed for one course of treatment, though once it's been reconstituted it's only good for one month.)

    Then my regular vet told me the Ronaxan can be crushed, no problem, so I went back to those next time my boy had a respiratory infection. The liquid Doxycycline was especially easy to give, as it had no smell or taste as far as I could tell, and so was no problem to hide in small amounts of food.

    Nausea or vomiting are quite common side effects with Ronaxan but can usually be avoided by giving it with food.

    Obviously something to discuss with your vet, but splitting the powder and making up only a fraction at a time often has medically acceptable margins. It's most commonly done with azithromycin suspension as that's only good for a very limited time once made up (and there's no small dosage tablet options).
