First a grey wolf is a mammal and they live in packs and wolves carnivores. This means that they are meat eaters. Wolves are warm blooded.
The male and the female, mate in January and February. The male fertilises the female’s eggs. The embryo is in the female for 65 days.
Soon after, the pups are born. At this point the pups feed from the female. During this stage, after about 4 months the pups begin to hunt for themselves.
Directly after the pups grow into juvenile pups. Meanwhile the juvenile pups grow into adult wolves. After this the adult male wolf mates with a female.
