When to call the vet?

I found this great resource online once about when to call the vet for your cat. It had things to call the vet NOW for, things that could wait until the next day, things that could wait a week, etc. I'm a bit of a freak with the cats, and tend to overreact about the slightest thing, and wanted to print this guide out, and now I CAN'T find it

Anyone know of it?

Hmm not sure of the exact site you may be referring to but here's one.
