First of all, there are additives in the juice sold on the market now. In fact, all animals, including people, should try to eat natural food and drinks. Especially if you read the instructions of fruit juice carefully, you will find that some brands or varieties have high salt content, not necessarily salt, but specifically high sodium content. This is very, very bad for cats, which will cause hair loss and even affect organ function.

Even if it is freshly squeezed juice made by ourselves, cats have no sweetness, and people don't need to "please" and "lead" it with sweet things. Or you think your cat lacks nutrients such as vitamin C and dietary fiber, and you want to supplement it with juice. This seems to be a sword walking sideways. It is better to give it some grains such as rice.

Of course, occasionally, in order to make him happy or he is interested in juice, it is no problem to let him drink a few mouthfuls.
