Bone infection in cats is a health problem that can be diagnosed late. Early diagnosis is crucial, and bone infection, which has chronic and acute types, must be treated with the correct approach. You can find detailed information about this health problem, which directly affects the quality of life of our furry friends, in our article.
What is Osteomyelitis (Bone Infection) in Cats? Osteomyelitis is a bone infection caused by bacterial or fungal infections in the bone or bone marrow. This condition usually occurs after a fracture or surgery. In some cases, an infection from another part of the body reaches the bone through the bloodstream, causing inflammation in the bone and surrounding tissues. Cats may not show immediate symptoms of bone infection, meaning it is often only noticed after the infection has become severe. If you suspect a bone infection, you should contact a veterinarian immediately. The earlier treatment begins, the better the results. In some cases, surgery or amputation may be necessary to treat bone infections. Treatments may require several weeks of hospitalization. Osteomyelitis (Bone Infection) Symptoms in Cats Bone inflammation in cats can have multiple symptoms. However, the most common symptoms include:

Symptoms of Osteomyelitis (Bone Infection) in Cats
Bone inflammation in cats can have multiple symptoms. However, the most common symptoms include:
• Lameness, • Weakness, • Fever. Different symptoms may also appear if an infection occurring elsewhere in the body spreads to the bone or bone marrow.
• Shortness of breath, • Discharge from the eyes and nose, • Vomiting, • Diarrhea are also among the general symptoms of bone infection. Swelling in the bone or joint where the infection occurs, various lesions, and discharge from soft tissues are also known as rare symptoms of bone infection. Osteomyelitis in cats can be acute or temporary. This condition can be short-term or chronic. Bone infection can occur in both bacterial and fungal infections.

What are the Causes of Osteomyelitis (Bone Infection) in Cats? Bone or bone marrow infection is most commonly caused by bacteria or fungi entering the body through normal routes of transmission such as unhealthy and unhygienic diet, exposure to other sick animals, or open wounds. Fungi or bacteria that enter the body reach other parts of the body, primarily the bones, through the circulatory system. The infection causes inflammation and pain in the bones and bone marrow. The most common causes of bone inflammation include injuries such as fractures, trauma, bites or claw wounds, post-operative inflammation, soft tissue inflammation, gum infection, and other infections.

Fungi or bacteria that enter the body reach other parts of the body, primarily the bones, through the circulatory system. The infection causes inflammation and pain in the bone and bone marrow. The most common causes of bone inflammation include injuries such as fractures, trauma, bites or claw wounds, post-surgical inflammation, soft tissue inflammation, gum infection, and other infections.
How is Osteomyelitis (Bone Infection) Diagnosed in Cats?
To diagnose bone marrow infection, the veterinarian needs to be provided with comprehensive information about the cat's general health, symptoms, and any possible events that may have caused the condition. This will provide clues to determining whether the condition is acute or chronic. If the infection has gone undiagnosed for a long time, new bone growth may be seen in the infected area. This growth provides insight into how long ago the infection occurred. In addition to a physical examination, tests such as a complete blood count and urinalysis may be performed to make a diagnosis. The results of these tests usually show the cause of the infection and the level of the immune system's response to it. In cases of fungal infection, the causative fungus is isolated and further tests are performed on the fungus to identify it. X-rays of the infected bones are taken to determine changes in bone structure and the presence of any chronic infection. Imaging methods such as ultrasound can clearly show the condition of the bones. A sample of fluid and pus may be taken from the infected area for further laboratory analysis. The treatment method to be determined to eliminate the bacteria causing the infection is decided in this way. Treatment Methods for Osteomyelitis (Bone Infection) in Cats When an infection occurs as a result of injuries in cats, these wounds must first be treated. Cleaning the wound and removing the dead tissue around it are the first things to be done. Afterwards, antibiotic treatment is applied until the infection is completely resolved. In cases where a fracture or crack in the bone causes an infection, the situation must be stabilized to prevent further damage to the bone and surrounding tissues. In this case, various implants can be used depending on the condition and location of the fracture or crack. This implant is removed when the fracture has completely healed. In cases where the crack is very serious, the likelihood of the infection spreading to other parts of the body increases. In such cases, it is necessary to consider how much bone and tissue damage there is. In cases where the damage is extensive and there is a risk of infection spreading, amputation of the infected limb may be necessary. Post-Treatment Recovery Process During the treatment and recovery process for osteomyelitis, the cat's activity should be restricted and it should not be allowed to move around too much. In the case of amputation, the cat's adjustment to limb loss is very important. During this process, activity restriction is also necessary. Depending on the severity of the infection, the recovery process can be long and costly. Acute cases respond better than chronic cases, which require long-term treatment along with surgical intervention. If improvement is not achieved with antibiotic treatment, additional samples may need to be taken to choose a more effective antibiotic. Similarly, if it takes too long for the fracture to stabilize, additional healing surgeries may be performed. In cats, laboratory tests and X-rays may be required to monitor healing during the treatment of osteomyelitis. It is necessary to strictly follow the veterinarian's instructions, from medication use to monitoring the process. Incorrect steps taken during the process can lead to failure of the healing process and the emergence of new complications. Cats need to have their activities restricted and be kept away from other animals and children. Providing a stress-free environment for cats during the healing process is recommended. Using a crate and keeping the litter box as close as possible can make life easier. Good nutrition is one of the factors that accelerate healing. Therefore, advice should be sought from a veterinarian regarding supplementary foods or changes in diet. In conclusion, the healing process can vary depending on the location and severity of the infection, the type of fracture or crack (if any), the cause of the infection, the surgical intervention performed, and the individual response of the cat to treatment.
