Can a kitten with rickets recover and avoid lifelong medication?

I am sorry to hear about your concern for Lio. Most kittens with this condition do have trouble walking and become weak after extended play. The condition can, however, be treated in most cases that haven't experienced broken bones by switching to a healthy balanced diet and exposure to sunlight. You can read more about this condition at https://www.merckvetmanual.com/cat-owners/bone,-joint,-and-muscle-disorders-of-cats/disorders-associated-with-calcium,-phosphorus,-and-vitamin-d-in-cats . It is possible this kitten was mildly affected and is improving with proper diet.

I think perhaps you're asking about Rickets Disease. Rickets is a disease of young, growing animals that causes soft and deformed bones. It is commonly caused by insufficient phosphorus or vitamin D in the diet. More rarely, calcium deficiencies are to blame. As in most diets causing defective bone formation, the cause is typically an imbalance in the ratio of calcium to phosphorus. Animals fed all-meat diets are commonly affected. It's very important to get him on a well balanced diet - I recommend Hills, Royal Canin, or Purina (although I don't know if they are available in Turkey) - to try to correct the issue. Prognosis is generally good, after an appropriate diet is started, unless he's started to have broken bones or his growth plates are affected. I hope that helps!

Rickets it is extremely rare in cats, especially if they are fed normally with commercial diets. I would really doubt this is the problem. Please complete your question describing the signs you are noticing to receive further advices from us.

Any commercial cat food should have the appropriate amount of calcium and calcium:phosphorous ratio to result in remineralization of the bone. This will not correct any limb deformity or fractures but should prevent these problems in the future. Veterinarians often recommend restricting activity to give the bones time to mineralize, but this often happens quickly ( within a month or so).

Correct of diet is the primary treatment for rickets. Many homemade diets for dogs are deficient in minerals and have altered calcium:phosphorus ratios. Therefore, a high-quality commercial food, or one designed by a credentialed veterinary nutritionist, is recommended. Brands of puppy food I recommend include Royal Canin, Hill's Science Diet, Purina ProPlan, and Iams. I hope this helps!

It looks like the inactal is a vitamin supplement and the taxim is a broad spectrum antibiotic. If the other vet was treating for a suspected infection in her leg, then the antibiotic will help. I recommend giving the medications as directed, but rest for a week is also a good idea. Katie doesn't know what rest means so making sure she rests will give her time for her injury to heal. Kisses to Katie!

It's a little difficult to see in your copy of the x-ray, but it looks like the left femur might be fractured. If the broken bone is above the knee then a cast won't help because it's not possible to stabilize the fracture. If they have recommended pain medication and rest I think that probably is the best option with a broken hip - kittens can heal quickly and it's possible that he will have decent function in the leg. If not, then a surgery called a femoral head osteotomy might be an option once he's big enough for surgery.
