I agree that's probably the case, but though Nagini is a snake, we 
can safely say she has some inherent magical ability.  Whether 
imbibed through Voldy or not, it's there (I don't think the name 
relation to the Hindu Nag was an accident.)  That said, I think the 
possibility that Nagini (and possibly other animals...Mrs. Norris?) 
can see through the cloth. 

Remember that the Invisibility Cloak is not some cloth that's been 
charmed, it's woven from the hair of the Demiguise, a creature that 
can become invisible if threatened.  If you check out Fantastic 
Beasts, it says this "ape-like creature" is from the Far East.  
Perhaps the Nag, as one magical creature, like to feast on the 
Demiguise, another magical creature.  That would explain why she can 
see through the cloaks...they'd need some way to hunt!  

That's my two cents...
