So lately I have wanted a Guinea Pig. I have emailed so many people and made some may phone calls. So today I had gotten an email about a dad and a baby Guinea Pig. I asked my mom and she got all pissed off.
She said, "Amanda, you will have to take a lot of responsiblite, you have to feed it, clean its cage, love it, and you have to do other stuff too. You didn't want to take care of Mr.Chips." Well, first of all, if I can take care of our dogs, I can take care of a Guinea Pig. Second of all, Mr. Chips was our class pet in the 2nd grade!
I really don't want to sound rude or like a bad kid, but she doesn't trust me. I can take care of every animal in the world. But she doesn't trust me, and I don't know why.
I want to prove to her that I can take care of things.
She is okay with me getting one, but she isn't happy about it.
I really don't know what to do.
I have gotten books and information about Guinea Pigs and a bunch of other stuff.

Make a pretend cage and / or other duties to prove you can do things without being told,

I have a 9 year old and I can tell you that I have to check to see that they are feed or they would starve to death after the first month, And I have to make him clean up all the cages or they smell so bad.

You may be mature enough, but you mom tells from your other duties, cleaning your room, taking out trash, or helping with dishes if you are mature to do things without being told

I am 13 and I don't know why she doesn't want me to get one. I do all the stuff you said to do, so I don't know what I need to do anymore.

I can tell you from experince that at 13 years old you will really want that Guinea Pig, and you will love it, care for it and feed it every day for a month or more, but gradually you WILL get tired and sick of cleaning it every day and it will be your parents job.

I had a rabbit years ago and I fell into the same pattern, I went from cleaning and feeding him twice daily, to letting my dad do it most days.

I have had a Hamster, and I loved it, I want more experience with animals. I really think it's funny that I can take care of our four dogs (everyone has a dog, were animal people :) ) I feed them, buy them toys, do everything for them, and yet, a Guinea Pig is way too much for me. It's crazy. But I must listen and be a good kid.

Maybe it's more the fact of your parents don't want any more animals in the house?

If they say no don't worry, you have about another 70 years of your life to buy a whole bunch of Guineas.

Do you really want to bring another pet into this home?

I wonder, do you still have to be asked to do any of the things you do? My brother cleans his room, helps with the laundry, walks the dog, and all sorts of other chores too. After he's asked about 5 or so times and threatened with being grounded.

Even if you are mature enough to have a guinea pig, as others have pointed out, it's a lot of work and it gets old. Maybe you can offer to pet sit for your neighbors when they go out of town, to gain more experience. Then it won't be a full time responsibility. Whenever they go out you can go over and feed and play with the animals. And take the dogs for walks. And if after a while, you still want a guinea pig, talk to your mom again.doing things that you know your parents will not be happy about, is almost always a bad idea.

Hey! I was in the same position you when I was your age. I'm 17 now and I know exactly how you feel. I cannot tell you how much I wanted a guinea pig as well... and like you, my mum and dad kept on saying how I wouldn't loook after it etc etc. But after about 5 months of persuading ( I brought books out of the library and did TONS of research on the internet, and generally wouldn't shut up about wanting one! ) they were finally persuaded into letting me have one. It took aaages though, and I knew that I would have to give my guinea pig the best life ever, so that this whole scenario wouldn't happen again if I ever wanted something else so bad as I wanted my guinea pig! In actual fact, my poor little guinea pig had t be put down 2 days ago because he had bladder stones and when he was in the operating theatre, complications arose and the kindest thing I coukd do was to have him put down. So I think you also have to be aware of how you would pay for treatment that your guine might have to have. Because your only 13, you prob won't have a job atm.. and your guinea prob won't need any treatment for a while so that aspect could work out quite nicely.
As for you wanting one, I am sure that you would do great in looking after one... if you know deep down in your heart that you would give youyr guinea pig the best life ever... then go ahead. Because from a personal experienec I know exactly how you must feel :) and I knew myself how much I wanted one and how much I would care for it. The other thing though... would you just be getting one guinea pig? Because they are VERY sociable creatures, and they do get really lonely if they are kept on their own . So you might have to consider getting 2... which given your circumatances might be a little difficult.
Anyway... good luck in getting your little pig, just keep on persuading !
