So 24 hours to get you back to life or your familar becomes becomes a normal snake.

Actually, that reference only states that they retain their spell knowledge for only 24 hours after the death of their master.
I came across this thread searching for the answer to this question, but with the assumption that the master DOESN'T get raised. There is nothing in the rules that I could find (and I spent several hours searching) that details what happens to a familiar after the master's death.
My read of the situation is that the former familiar obviously loses access to any abilities related to actually having a master, but otherwise remains a magical beast. Which creates all sorts of problems with communication as they now cannot be affected by speak with animal. Tongues doesn't works because "Tongues does not enable the subject to speak with creatures who don’t speak." You can't use Awaken because they're not an animal any more. Familiars kind of get the short end of the stick if their master dies on them.
But has anyone found anything more on this subject?

Once dismissed, an animal familiar is just a normal animal of its type (a special familiar from the Improved Familiar feat reverts to a normal creature of its type). Whether or not it wants to remain with you is up to your GM and probably based on how you treated the creature while it was your familiar.
I for one would find it odd if your master's death left you more magical than being dismissed. It's not impossible---arguably the familiar is still attached to its master's dead soul---but definitely odd.

On a related note, it looks like the PCs will be dealing with the communication barrier by crafting a Gold Nodule Ioun Stone for it.
