Hi everyone,in February Penny weighed 2.45kg but when she went to the vets last week she weighed 2.18kg. The vet didn't seem overly concerned about her weight loss but this seems quite high to me! We are taking her back to see a different vet the week after next (the next available appointment) Does anyone have any suggestions of what could be causing this? She is spayed, the vet said her teeth were fine and her appetite hasn't changed. Should I be asking for a blood test? She's almost 2 years old.
