Hi Enagaland , welcome to the forum

It is a good idea to learn how to use the search function
also it would be a good idea to read all post in the safety section

here is a sample about Nitric acid , but please do read all.

please also read Hoke´s book about refining ( it can be downloaded for free a link is in my signature )

Since you ask I assume you do not have safety equipment and hood / scrubber etc etc. Therefore do this outside, Nitric fumes will not only kill the cat it will also kill the neighbor and yourself.

Therefore please take safety serious

Using HNO3 (nitric) in any process can be dangerous. Under "build your own equipment" there are some post about building and using fume hoods and scrubbers, you might want to check them out. It is always better to be safe then sorry. Butcher has wrote some great post on NO and NO2 you might want to read also.
