Luna
PetNoter AI
Luna has put on weight this year. Should I worry?
PetNoter AI's suggestion
Monitor at home
Keep an eye on it and contact a vet if it gets worse.
Luna's weight log shows a steady rise since March. A slow gain like this is common in indoor cats, so keep logging her weigh-ins and ask your vet to check her body condition at her next visit.
Not a vet. In an emergency, contact a vet right away.
