Answer: We all know that the foods served warm have more flavor then when they are cold and that there are smoother. Certainly for the cat the acceptability of canned food increases with its temperature, up to blood heat (around 140F or 40C) which is the temperature at which its natural prey would be eaten. Further increase in temperature beyond this point result in a sharp reduction in acceptability, and cats are very caution about tackling any food much hotter then 122F (50C).
There seems little adult, therefore, that your cat will enjoy its food more if it is served warm, and the food temperature can be critical in persuading a sick or convalescent cat to eat. Obviously, the warming of foods is only possible with those having a high moisture content. Attempts to heat up dry or semi-moist foods may result in them being burned and rendered quiet unacceptable.
