Feline fibrosarcoma is a rapidly progressing and potentially fatal form of cancer in cats. It may develop without particular cause in older cats, but there are two specific types of fibrosarcoma that typically occur in young animals. In the first case, a mutated form of the feline leukemia virus may lead to fibrosarcoma. In rare situations, fibrosarcoma may develop at the site of a vaccination. Because of the serious nature and health risks associated with this form of cancer, it is important to recognize the symptoms as quickly as possible so that you and your vet can diagnose and treat the condition.
Unusual Growths
Fibrosarcoma is typically characterized by a surface-level skin growth. Your pet may display an unusual lump or mass on any part of his body, although it is a good idea to keep an eye on the site of any vaccinations. Most cats receive vaccinations in between the shoulder blades, so this is a relatively common site for fibrosarcoma tumor growth.
The growth itself may not be visible. In fact, it is best if you catch the tumor before it has grown large enough to see. The best way to determine whether your cat has any unusual tumors is to do a quick examination every couple of weeks. Get in the habit of brushing your cat while he sits in your lap. Although he may be uncomfortable at first, most cats quickly grow accustomed to this routine. During that grooming time, carefully feel over his body for signs of any unusual lumps or growths.
Open Sores and Discharge
Another common sign of fibrosarcoma is a weakened immune system and regenerative properties. Your pet may develop infections or open sores that take a long time to heal. Be on the lookout for unusual discharge from any of those sores or any other orifices.
Loss of Appetite and Weight
Cancerous cats frequently experience a reduction in appetite. As a result, they oftentimes lose weight, which can affect their body and its capacity for fighting off unrelated diseases. Ensure that your cat is eating all of his food. If you have multiple cats that share a bowl of food, be careful that one cat isn't eating any more than the other. Because cats are naturally picky eaters, you may wish to experiment with other brands or types of foods to make sure that his tastes haven't changed.
Lameness or Difficulty Moving
If your cat has a tumor or growth on his legs or abdomen, he may have a hard time walking, sitting or moving around. Be aware of any changes to your pet's mobility. Take note if your pet has trouble climbing up or down stairs, if he is reluctant to play or if he walks with an unusual gait.
All of these symptoms are common to feline fibrosarcoma cases. However, your pet may experience only some combination of these and other warning signs of the disease. Take the time to check your cat for signs of fibrosarcoma and other cancers, as a prompt diagnosis and treatment is crucial to your pet's survival.
