Social grooming, also called allogrooming, is a sign of social bonding and is associated with security, trust and love when cats lick their humans. However, topical medicines can cause harm to cats who like to lick their people. The FDA recently warned people about the possibility of fluorouracil poisoning in pets <Link>.
Catnip’s eStaff shares information about fluorouracil and other topicals that can harm cats if licked from an owner’s hand or body. It is good information to share with cat owners on social media or in newsletters.
