A cat in the attic, hmmm...
Sounds to me like a case of a feline Upper Respiratory Infection... Cats are nosey things, and I'm thinking that depending on your attic, your kitty got a snootful of insulation dust; Depending on what kind (fiberglass, blown cellulose, etc.)...
I found this on google...
"We adopted a family of feral cats a couple of years ago. They were
kittens at the time we adopted them, but they've retained much of their
wild characteristic. Nonetheless, we are very attached to them.
The problem is that one of them, Pixel, has a chronic upper respiratory
problem that presents
by her sneezing violently for extended periods of
time. Also, there is a loud snuffling sound to her breathing, probably
due to her nasal congestion. I'm sure that the problem is viral, since
she has just finished a two week course of Amoxicilan 100mg (1/2 tab/day).
What I'm wondering is: is there any treatment for this kind of
condition? I've been told that the disease is probably a form of feline
Herpes, so are there any anti-viral drugs that can help?
I was hoping that she would outgrow the condition, or that it would enter
into temporary remission, but instead it seems to have plateaued.
I appreciate any comments you may have, Rob
Answer: Rob-
Most of the time chronic upper respiratory disease like you are seeing is
the result of early severe viral infection that damages the nasal
turbinates, making it easy for secondary bacterial infections to occur in
the nasal passages. In the case of herpes virus, the virus also sticks
around and causes intermittent problems.
There are no really good systemic anti-viral agents for cats that I am
aware of at the present time. It can be helpful to give l-lysine,
500mg/cat/day. This is an amino acid that interferes with reproduction of
the herpes virus and which can suppress recurrences of the virus if it is
supplemented continuously. Some vets believe that interferon administered
on a seven days on/seven days off schedule is helpful.
Since you can't get rid of the virus, the next plan of attack is to treat
for the secondary bacterial invaders. There are lots of possible choices in
antibiotics for this. Currently, fluoroquinolones like enrofloxacin
(Baytril Rx) and orbifloxacin (Orbax Rx) are commonly recommended, as is
azithromycin (Zithromax Rx). The major advantage of azithromycin is that
it appears to work well even when given every other day or even every third
day.
Using a nebulizer to help moisturize the nasal passages can be helpful.
This is done by putting a cold nebulizer directly in front of a crate with
the cat in it or putting it in a small room with a nebulizer (like a small
bathroom). Decongestants seem to help some cats. We have used
pseudoephedrine orally and neosynephrine nasal drops. Sometimes this seems
to help but not always.
It is likely that Pixel will have this condition for life, even with
treatment. Some cats require l-lysine and/or antibiotics for life to
control the snuffling."

I'm pretty sure that might be it; Hope your kitty will be fine in short order
