Homemade diets are a type of elimination diet, which are made specifically for the cat with allergies, either by the owner or a third-party person like a chef.[11] Studies suggest that commercial elimination diets may still react negatively with a cat, even if they are devoid of the target protein/other problematic foods.[11] Many pet owners, for this reason, choose the homemade option, as it allows them to personally identify the pet's history, tailor the diet with various ingredients, and consider the process a bonding experience.[2][11] Some drawbacks to a homemade diet are the time needed to shop for the ingredients and the potential financial setback.[9]
