There is a lot of unanswered questions revolving around the Evolved Companion
that I cant seem to find an answer to anywhere else. Although I've found this helpful but it doesn't address everything. For example the evolution Magic Attacks states:
"An eidolon is infused with magic, allowing it to treat all of its natural attacks as if they were magic for the purpose of overcoming damage reduction. If the summoner is 10th level or higher, all of the eidolon’s weapons are treated as the alignment of the eidolon for the purpose of overcoming damage reduction."
How would this be handled or would it just be ignored? Another Example is the Claws evolution which says:
"The eidolon must have the limbs evolution to take this evolution."
I ask this because I'm utilizing the evolution pool quite readily to boost the power of my companion. In particular I would like to give my big kitty an extra pair of claws on its back legs and magical attacks. But have no clue if its even possible due to wording. Is there something I've been missing that tells you how to solve for this?

One thing you should note is that a creature cannot use claws on the back limbs if they use those limbs to walk around, this is a limitation on a creature's natural attacks, as seen on this FAQ entry:
Example, a tiger (big cat) actually has four claws, but can only attack with two of them at once. The other two claws can only be used with the Rake ability. So, even if your GM does allow you to take extra claw attacks, the creature cannot use them (except for raking), unless he also creates a house-rule to ignore this limitation.
That said, looking at Evolve Companion we see that the possible evolutions are limited to the form of the animal:
This means that you cannot take the Wing Buffet evolution if you do not have wings, or Tail Slap and Sting without having a tail, or, like the example given on the feat, be used as a Mount without being of the appropriate size and form (quadruped/serpentine) for that.
If the creature does not gain pounce or rend from another source, adding extra claws to her legs will not make any effect on her combat statistics. A wolf would benefit from claws on the front legs, for instance, but a tiger would not gain anything from adding extra claws to her feet.
