Great to hear you are adopting from a shelter!
Some advice when you go.
Don't rule out older cats. There are plenty of affectionate, playful cats that are in need of good homes. Some come from homes where the owner died or could no longer care for them. You know what you are getting with a cat vs. kitten.
I have 2 cats and I'm glad I have them in pairs. They keep each other busy when I am away at work for long hours, they sleep, play and groom with each other.
Indoors is a MUST.
Great advice from other posters about care and maintenance.
If I could add anything it would be to make sure both cats have plenty of fresh water. I usually change their water bowls 2x a day.
Best of luck.
Here are my 2 boys.
