Focus on gentle care: soft bedding, easy-to-grasp food, and low-impact exercise. Regular veterinary checkups and warm companionship will keep your senior friend comfortable and loved.
Mature Companion (3 - 5 Years)
Your guinea pig is likely three to five years old, entering mature adulthood. You may notice a calmer disposition and some changes in fur texture or eyesight.
