Building a shape shifter with interesting rules

(they have to get the mass from somewhere though, usually from eating the subject). would this be mitigated mass conservation -10%?

Can they turn into large invertebrates, such as octopus or giant/colossal squids, which can surpass human size? And are they similarly unable to turn into small mammals, whether housecats or Etruscan shrews?

I would say they can function as large invertebrates, though they would have extreme unfamiliarity with the shape at first. They can't imitate small mammals.
