i feed Walle pet promise cat healthy weight and ageing, but now the pet store says that they are not going to make it anymore. i was wondering what the best food to feed him is. should i feed him spikes delight? is it really better then cat food? does anyone have any suggestions on what to feed him? i have plenty of food left for him but im not sure what to buy after this is gone. i know i need to switch food slowly so he doesnt get sick but i need to know the best food!
