See, I don't know. This gets into a whole sticky gray area. Muto's a mess.
See this discussion, to see why I'm stuck in analysis paralysis.
I want to say yes, to this, in this case). Because it is, for the duration of the spell, a human body. I do have a problem with a person under the effect of a MuCo(An) spell being affected by any subsequent animal spells for the duration of the MuCo(An) spell. That seems broken to me, and there's a reason that people have Souls, and they anchor us to our human form, being in the image of God. Think the Limit of the Soul applies here? I kinda do, or find it to be a good argument for not allowing animal spells affect people, period, as the description of the Animal form states.
I only now realize that the thread has gone a bit off the rails, because the only place I can see the Shape and Material bonus applying is during lab work (or am I missing something?). I wouldn't let a Magus muto something for 13 weeks of work and get away with it while he's enchanting it. I'd probably do something like at the end of the season he realizes he can only access the power he wants when he changes the shape to the form he'd been working on all season, so he needs to add another effect or something. I dunno, it's a huge mess I really don't want to get into, but probably need to because of Alexei's spear, and didn't really think of the full effects. Grr...
