Hello,My 4 year old cat, used to eat Whiskas croquettes, but for 2 weeks I changed brand for Nature Bridge. Since, my cat vomited, is weak and a strong odor emanates from the litter.Do I have to continue feeding it with the new brand the time it's used to? Or is it a sign of a real indigestion in relation to this product?Thank you for your reply
Indigestion change brand of food
