How to explain to my mom why I want a rat?
So... for 3 years already I've dreamed of getting a rat. By now I have decided that I want a pair of female ratties ;33 But, here's the deal... when I do finally work up the courage to ask my mom if I could possibly get rats... what do I say when she asks WHY I need rats?
I can't say I just want a pet/companion, because I already have pets. I can't say I want a rodent because I haven't had one, because I do - I have mice. I can't say I want a pet I can train, because I have a dog. FYI, I have a cat, two mice and a dog.
Frankly, I can't explain why I want rats either. I just... do. I'm a compelete animal freak. My life circles around them XD So yeah. But really, I can so imagine the conversation that will happen.
"Hey mom what's up... uhh... what do you think, could I please get rats?" - pets question and answers,www.5d2d.com
"What? Why? Why do you need rats?" -
"uhh..." -
"Why do you need them, you already have mice, a cat and a dog." -
"Well... ummm..." -
"Well?" -
"because I.. like... them?"

...yeah. I need your help!
answer:
I'm afraid mom has you there - rats are not a need. No pet is. If you can't think of a good reason to get a rat (such as "i have the time, money, and experience needed to care for them") then you're SOL. Again, pets are a want. Not a need.

Mom may just not want you to have a ton of pets in the home and considering she pays the bills.....

I wasn't able to have rodents until i moved out because my mom is terrified of them. When i moved back in to save money i made a deal with my mom - because i was over 18 she couldn't say a thing about what i kept in my room. The only exception was if the animal i got affected them in any way. pets question and answers,www.5d2d.com

So my rats where able to come home with me to live out the rest of their lives. Then when they passed i got mice. When they passed i got gerbils.

But if you're under 18 and/or not employed, you're at mom's mercy. Just explain to her that you love animals and would enjoy have rats as well. Or maybe make a deal with her - when the mice go, rats come in (mice don't naturally live that long after all.)
