When I adopted Kiky, I adopted her from a non-profit organization that rescued kittens and older cats and fostered them until they were adopted.
She was handed to me with a MASSIVE amount of paperwork, contracts, health information, when and where was she found, who found her, what medical procedures had she had, or which ones she needed, etc. I didn't pay attention to the necessity and urgency of the paperwork, until I had to take her for her first vet appointment.
The vet asked me a bunch of questions in which the answers were in the paperwork, but everything was son disorganized I got frustrated trying to find the information. I then decided to redo the information package they hand out when they successfully complete an adoption.
