The Range function The built-in range function in Python is very useful to generate sequences of numbers in the form of a list. The given end point is never part of the generated list; range(10) generates a list of 10 values, the legal indices for items of a sequence of length 10.
Male kittens are usually neutered at between 4 to 6 months of age. However, the AVMA has endorsed early age neutering of dogs and cats 8 to 16 weeks of age. You and your vet can decide what is the best time starting in a few weeks.
The kittens were divided into three groups: 1  Group 1 (11 kittens) were neutered or spayed at 7 weeks of age. 2  Group 2 (11 kittens) were neutered or spayed at 7 months. 3  Group 3 (the control group of 9 kittens) were not neutered until maturity and after the completion of the first phase of the study at 12 months.
