Willow was about a year old when I got her from the humane society 5 years ago, so she's about 6 years old now. Currently, I'm feeding them Precise Foundation. Should I be thinking about switching to the senior formula? What are some reasons to switch? Or should I just leave them on their current food, since they seem to be doing okay?
At the age of 10, I'd have an exam and ask for a senior panel to be done...let the vet know you want baseline results on Spot's kidney function, and Thyroid function. I would consider changing him to a lower phosphorus, slightly lower protein, good quality food and consider doing whatever you can to increase his water intake - i.e. getting a water fountain for pets, increasing amount of canned (good canned) food in the diet and decreasing the per centage of dry.
Your gal who is about 6 - I'd also think that increasing wet food versus a total dry diet would be good, though I would not change her diet to a "senior" formulation just yet.
Just my opinions
