Gooseberries

Been away for a long weekend...(eldest daughter's graduation...she now has a Masters degree to add to the several others she has collected..how she does it with working full time I don't know)....come back to find that something has eaten all the leaves off two thirds of the one big goosegog bush i have, it has not touched the fruits . No sign of any creepy crawlies or fingus or anything untoward but what do i do now? Haev collected all the fruits this morning but do I severely prune bush to stop the munchies or what?
