Explanation: Hi,Victor cannot digest nor understand his creation and his first reaction is rejection, particularly as he sees that in a way the creature is trying to imprint and get affection from his creator.
Victor regrets creating the monster which killed his family and especially his love. He wanted to prove that he was smart enough to create life, but instead he created a monster.
He regrets bringing his creature to life because the monster is terrifying to him. the monster does a lot of stuff that victor is not okay with (for example, killing his little brother & framing a family friend of theirs, etc). he wishes he wouldn't have created the monster, so none of that stuff would've happened. he thought that's what he wanted to do, was create a monster because he was so smart and capable of doing so, but in all reality what he created ended up running his life.
When the large cat repeats the same words 'Better wait till Martin comes' It creates excitement and curosity in the readers mind that who this Martin is? So, the effect that this repetitive words give to the story is that it pushes the story to it's most exciting part.
