How can i convince my mom to let me get a hedgehog?
Hello~! I REALLLLLLLLLLLLLLLY want to get a hedgehog! i found this cheap hedgehog from SPCA(Animal shelter) and i told my mom about it and she said no she said she is afraid of mice. so i said Hedgehog doesn't look like a mouse,and it's easy to take care of them but my mom still SAYs NO!!!!!!!!!!!! (My report card is good my lowest mark was 80 and i made it to honour roll) SO PLEASE HELP ME HOW CAN I CONVINCE MY MOM?
take your mum to the shelter and show the hedghog she may fall in love with it or hate it. You have to remeber it's her house so respect her choice.
