Hi gang ... I'm in Arizona and about 6 of the cats in my colony have long hair and Summers coming quick out here ... has anybody ever used anything on food to help with hairballs or is it just not necessary? these are fairly news cats to me (all TNR'd but weren't around last Summer) and already with it warming up i see balls of hair with weeds ect stuck in it hanging off a couple of them ... So I know there will be a lot hacking up hairballs. Just seeing if I could do anything to make it easier for them.
