Mr C didn't get clingy until recently ie age 13.5. When it started I thought he was ill - the vet advised me thus:
Me: 'painfully weak, not moving much'. Vet: Diagnosis 'lazy'
Me: 'only gets off sofa to go to bowl'. Vet: Diagnosis 'greedy'
Me: 'his tummy feels limp' Vet: Diagnosis 'fat'.
These so-called experts know nothing.
