I have a 17 year old Ragdoll whose health is on a rapid decline: not eating as much, missing her litter box, horrible arthritis, back legs give out when she walks. She recently got a Solensia shot for her arthritis, but it does not seem to be helping. The vet said I could let her go at any time I am ready - I don't think I could ever be ready to let her go. For those who had a fur baby in a similar situation, how did you handle it? Did you get a second opinion or try another medication? How did you know it was time to let them go?
