Hi there,
Could you add a category for "Small Animals" within the current Home & Garden > Pets parent category.
This would be a generic category for items that are common to multiple types of small animal: rather than puting it into multiples of the currently existing currently existing Rabbits/Gerbils/Hamsters/Guinea Pigs/Rats/etc
Would allow someone who has a particular type of small pet to find an item that may currently only be listed in one of the other categories. eg: Someone with a hamster, might not necessarily look in the Guinea pigs category even though an item may be suitable to both.
Cheers,
John
