Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Billy is breeding mice for an experiment. He starts with 8 mice, who each have 6 pups. When the pups grow up, all the mice have another 6 pups. Then each adult mouse eats 2 of their pups due to the stress of overcrowding. How many mice are left?


### Response:
 Au départ, il y a 8 souris.
Chaque souris a 6 petits, donc il y a 8*6=<<8*6=48>>48 petits.
Après que les petits grandissent, il y a 8+48=<<8+48=56>>56 souris.
Chacune des 56 souris a 6 petits, donc il y a 56*6=<<56*6=336>>336 petits.
Ensuite, chaque souris adulte mange 2 de ses petits, donc il reste 336-56*2=<<336-56*2=224>>224 petits.
Il reste donc 56+224=<<56+224=280>>280 souris.
