I always find my cats go through a cycle of eat less (this isn't my food, so I'm not eating it) to eat like they have never seen food before (ok...I'm starving...oh, this is good) cycle when introducing new foods....especially when going from dry to wet or wet to raw. Usually it evens out after 4-7 days as their digestive system gets used to the new food and how to process it.
If you think about it, the dry food would sit in their tummy longer...so they are used to that sensation. Wet moves quicker, so the cat feels nothing in the tummy, so demands more. Eventually they get used to the feeling. Same thing happens with wet and raw. Raw moves faster, so I must be hungry again.
