Many pet owners want to be more involved in the growth of their kitten. This can bring much joy and afford people an insight into how organisms like cats develop. There are marked differences, for instance, between male and female cats in terms of weight and age. This might seem obvious but cats may look visibly very comparable in weight regardless of sex. It is only when they are weighed that the differences then become apparent. Depending on the breed of the cat it males and females may overlap in terms of weight, with some breeds of male weighing in the same category as other species of females. Clearly, this can be perfectly healthy for that breed and there may be nothing to worry about, but checking with a vet or another informed source will prove enlightening.
When born, kittens weight approximately the same weight at between 0.1 and 0.3 kilograms. As they grow older male and female cats typically take divergent paths so long as they are healthy. At 1 month old most male and female kittens will weigh around half a kilogram with reasonable weights either side being perfectly fine. When it starts to put on more weight at around 5 months, it will weigh around 2 kilograms, but the acceptable variations can be quite big. Anything less than 1.5 kilograms may be a sign of trouble while anything over 3 is probably overweight. At 1 year weights will average at around 3.7 kilograms with anything between 2.5 and 4.7 being acceptable.
