Rehoming 1 year old cat

Recently came to be looking after a cat named Star, she is a year old next month. Previous owner passed away but unfortunately she isnt getting on with my dogs. Might be best to rehome her with no dogs. I don't know about vaccinations but I know she hasn't been spayed. Free to a good home. No microchip as she has been an indoor cat all her short life, though she has been wanting to get out.
