A 10-year-old cat is equivalent to a 56-year-old human. A 10-year-old cat is already an old man and may suffer from physical sluggishness, loss of appetite, weakened resistance, etc. At this time, the owner needs to supplement the cat with nutrients, vitamins, and calcium to avoid the loss of nutrients and water in the body. At the same time, it can alleviate the aging of cats.
