Changing Diets
Gradually transitioning onto a new diet will minimize the risk of stomach upset or other issues. In order not to overfeed – check the feeding guidelines on the new food and the recommended amount for the cat’s weight (assuming the pet has a good body condition score).
Gradually replace ¼ of the current food with the ¼ of the new food every 2nd day using separate bowls for the current and new foods – do not mix them in the same bowl. This allows cats to choose between the foods rather than having the change forced upon them, which can lower stress. After 7 days, the switch over to the new food is complete.
If a pet is susceptible to stomach upset, it may be beneficial to transition over 10 days.
