Why does the author say , " Toto was not the sort of pet we could keep for long " ? ( This question is from moments book chapter - The Adventures of Toto )

Dear Student,

Toto was a very mischievous pet. He kept damaging articles in the narrator's house. His family could not bear the loss of clothes and other such damages caused by Toto's mischief. Therefore, he was not the sort of pet they could keep for long.

Regards,
