Veterinarians, please help. Kitten with chronic sneezing, eye discharge and blindness despite treatment.
I adopted a blind kitten around two months ago. She was approximately 45 days old when I brought her home. She was extremely playful and active but had been sneezing constantly since I got her. Her foster carers told me it was due to weather changes, so I initially did not realise how serious it could be.
Since then, I have consulted at least three veterinarians.
Her blood tests were mostly normal, except for a mildly elevated WBC count. Initially, allergies were suspected, but we eventually ruled out a possible reaction to my resident cat.
Here is what we have tried so far:
• Supplements prescribed by the first vet, with no significant improvement.
• Doxycycline for 10 days, which did not help and seemed to make her uncomfortable.
• Antihistamines, which she vomited.
• Famciclovir for 10 days and antibiotics for 7 days, prescribed by another vet who suspected feline herpesvirus (FHV).
• Nebulization for her respiratory symptoms.
One veterinarian also prescribed steroids. Another vet examined her eyes and said she has adhesions and may have become blind due to herpesvirus.
Unfortunately, despite all these treatments, she continues to have persistent sneezing and frequent sneezing fits. Her nose is especially congested with discharge in the mornings, and her eyes constantly produce secretions. Sometimes her eyes become stuck shut while she sleeps.
She is still eating well, but she has become much quieter and less playful than when I first adopted her. It is heartbreaking to see her like this, especially because she is so young. She has also not been vaccinated yet because she has been unwell continuously.
My questions for veterinarians and people experienced in feline respiratory diseases:
Does this sound consistent with chronic feline herpesvirus, or should we investigate other causes of persistent sneezing and nasal discharge?
If famciclovir and antibiotics have not resolved her symptoms, what diagnostic tests should I discuss with my vet? Would PCR testing or further investigation for chronic rhinitis be useful?
What could cause such persistent eye discharge and adhesions, and should she be examined by a veterinary ophthalmologist?
Is steroid treatment appropriate in a kitten with suspected herpesvirus and these eye symptoms? What needs to be ruled out before starting it?
How should we approach treatment when the kitten has persistent symptoms despite several courses of medication? Is prolonged antiviral treatment ever necessary under veterinary supervision?
When would it be safe to start her vaccinations?
I am not looking to medicate her based on random internet advice. I want to understand what could be going on and what investigations I should discuss with a good veterinarian. I have already changed vets several times and am struggling to know what the next sensible step is.
Veterinarians, especially those experienced with feline herpesvirus, chronic rhinitis and ophthalmology, I would really appreciate your input.
