I'm new to the forum. I've been wanting rats for quite a while now, but once my sister and I got the option to get a rodent, she was so terribly insistent to get a guinea pig, that we got the guinea pig instead of rats. We've owned the piggy for three years now, and she's in good health. I have not really ever had interest in the guinea pig, and it seems my sister has the attention span of a fly. I seldom play with the piggy, yet I do pet it on occasion, clean the cage an feed and water her. My mother also helps with this on occasion, and claims that I am not responsible enough to have a rodent ever again. Another issue I need to get by is my fathers opinions. He agrees with my mother, and didn't want the rodent we already possess in the first place. I've shown him cute pictures of rats on the Internet, yet due to an issue he had in the past with these particular rodents. I really need help convincing. My mother, because generally if she has an opinion, he will agree. I know I'd probably have o wait until the guinea pig passes, but trust me, I'd never purposely kill her, and I'll be patient and wait for her to live a full life without suffering. I just need advice on how I'll convince my parents either now, or when the time comes. Thank you, in advance.
