2nd interview tomorrow but I kinda hate PetSmart… I just want experience with animals

I LOVE animals. Small, big, feathered, scales, fur, 6 legs, I love all animals. Loving animals has been part of my identity as long as I can remember. I have my second interview at PetSmart tomorrow, I am excited and scared. Scared of selling goldfish along with 10 gallon tanks and the rainbow colored hamster cages and all the other harmful products… but I need a job and my dream is to be a dog groomer and I think it will be good for future resumes. Is there any other employees with these feelings who are sticking it out? Can I get some advice on how to handle it incase I get the job?
