Iâ€™m so sorry you have to consider such serious possibilities. This is indeed devastating.
Iâ€™d like to ask you, has kitty been on some kind of medication that could damage the inner ear?
Also, has your vet considered other possibilities, for instance vestibular disease, and vestibular disease associated with the fungal disease cryptococcosis? If not, please be sure these possibilities donâ€™t get overlooked.
Peripheral vestibular disease referable to otitis media/interna was the main reason for presentation in three cats with cryptococcosis. In two cats, Cryptococcus neoformans var neoformans was isolated from the tympanic bulla. In the remaining cat, otitis media/interna was considered to be secondary to occlusion of the auditory tube by a nasopharyngeal granuloma associated with a C neoformans var gattii infection. This report emphasises the importance of maintaining an index of suspicion for a fungal aetiology in cats with signs of otitis media/interna, particularly in countries with a high prevalence of cryptococcosis. The presence of C neoformans may be overlooked with potentially fatal consequences where only standard methods for bacterial isolation are used to examine samples obtained from the middle ear.

|How do cats become infected with Toxoplasma?
Although cats can be infected by the same means as humans, the most likely sources of toxoplasmosis in cats is from eating mice, birds, and other small animals that are infected with the Toxoplasma parasite. For indoor cats, the most likely source is uncooked meat scraps. When a cat is exposed to Toxoplasma parasites through the consumption of infected meat or tissues, the cat can eventually excrete millions of Toxoplasma oocysts in its feces each day. This release of oocysts can continue for up to two weeks. Oocysts in feces become infectious (reach Stage F) after one to two days. Since most cats do not leave feces on their fur for two days, it is unlikely that humans become infected from direct contact with cats themselves. Because cats usually exhibit no signs of illness while passing oocysts, it is difficult to determine when a particular cat's feces may be infectious to people or other mammals. Most adult cats will not pass oocysts eve year. Although the majority of infected infants show no symptoms of toxoplasmosis at birth, many are likely to develop signs of infection later in life. Loss of vision, mental retardation, loss of hearing, and death in severe cases, are the symptoms of toxoplasmosis in congenitally infected children. Ideally, women who are in frequent contact with cats should be serologically tested for Toxoplasma gondii before becoming pregnant, because, if they are already seropositive, they are not at risk of asymptoms of toxoplasmosis, there have been cases in cats associating toxoplasmosis with pneumonia, liver damage, and loss of vision. Why some cats show symptoms and other cats do not is not known. Concurrent infection with other diseases (feline leukemia, feline AIDS) can aggravate toxoplasmosis in cats. Treatment can be effective if the disease is diagnosed early. A blood test for Toxoplasma antibodies helps in diagnosis of toxoplasmosis in sick cats.
To help prevent Toxoplasma infection in cats, follow these steps:
â€¢\tKeep cats indoors and do not allow them to hunt rodents and birds.
â€¢\tFeed cats only cooked meat or processed food from commercial sources.
At present there is no vaccine for toxoplasmosis in cats. Efforts are, however, underway to market a vaccine to prevent Toxoplasma oocyst shedding by cats.

I pray that your kitty doesnâ€™t have a brain tumor. In any case, please, talk to your vet about a referral to a specialist as soon as possible.
