I have an indoor only cat and have chosen to discontinue vaccinations for 
him.  Doesn anyone have an opinion on this?

My cat is indoor also, however, she will run out on occasion, so I do have 
her vaccines done.  Plus... she has to have her rabies by law :)

I understand about the rabies, and will most likely get that for him when 
he is due.  But he has had two negative reactions in the past to the usual 
vaccines, so I think maybe it would be best to discontinue giving them to 
him.  He goes outside when the weather permits, but he never leaves the 
backyard.  I think his risk of contracting anything is probably low.
