How Much Should A 3 Month Old Kitten Weigh?

The average weight of a 3 month old kitten should be between 4 and 6 ounces. Sometimes the kittens may weigh less than that at this age because they are still growing. The best way to know if your kitten is gaining or losing weight is to take it’s temperature every day, which should ideally be taken first thing in the morning before it has eaten anything (it should read about 100 degrees).
