We'd be interested to hear from you

We are interested in hearing from any organization that would like to join us in our journey to improve the health and wellbeing of companion animals.

The Meaning of Carus

The Latin meaning of Carus is ‘beloved’ or ‘held dear’. The verb ‘caress’ originates from ‘cara’ and the human contact of stroking or touching a pet in a loving manner is something we believe is strongly represented in our name.
