how to persuade my mum for a hamster?? help please?
right i am going to make a presentation but what else can i do that works i am going to ask soon please and cute hamster photos for my presentaton please.

This is what i did to get a hamster: (My mom is hard to convince and this worked!) Here are some tips:
1. keep your room clean chores around the house to get extra money so u can buy the stuff yourself
3. Show responsibility
4. be mature
5. write essays and add up the total of all the supplies you need. It makes you look responsible 😉
6. they only cost $10-$20
7. they dont smell unless u dont pick up their pee and poop
8. they DONT carry diseases if you get them from a reliable pet store
9. dwarves are smaller so they should be easier to deal with and their poop is smaller 😉
10. They can stay home for a few days, you just have to feed them for the amont of food for the amount of days you wouldnt be there. Also if you were traveling, you can always take them with you. If you have a traveling cage that you can get at a pet store made for traveling 😀

Good Luck!
