Rust Database

How can I find out my cat’s birthday?

I want to throw my cat a surprise birthday party this year. The only thing is that I don’t know when my cat’s birthday is. I got the cat from an adoption place so I didn’t get any papers as far as I can remember (I don’t have a working file cabinet as of yet but I will soon so don’t worry, the previous one I had gotten was rusted slightly but I repaired it)

Also I want to try and find out my cat’s rising sign (ascendant) so I am gonna need to know the cat’s birth time as well.

Is there some kind of government database that maybe has a website where I can try and look this stuff up? Or who should I contact? The adoption place?
How accurate is the vet? Like down to the day or down to the minute? Can they use something I’ve heard about once called carbon dating or DNA sampling or something? How accurate would that be?

no one keeps track of cat births
the adoption place is only an estimate sometimes
you can celebrate his birthday as the day you got him.
