Our two 14-year-old tomcats were marking and urinating all over the apartment. Despite thorough examinations and giving Clamicalm for a longer period, nothing helped. We were at the point of giving both cats away. After a tip (too much sugar in Felix), we slowly replaced the wet food with RC Calm. For a week now, they’ve only been getting RC Calm, half the meds, and they’re dry :-) Otherwise, they’re also very peaceful and affectionate. For lack of an alternative, they eat it.
