My best, hmm? Let's see..
~Rats groom themselves, and eachother all day long. They're one of the cleanest animals I know of besides cats.
~They're caged animals and can be put away if not being watched.
~They can learn tricks, come when called, be potty trained easier than dogs, I even saw a video of two rats that learned to play basketball. Teach your cats that one, ha. http://www.youtube.com/watch?v=41ZW0OGp4HE
~You can actually buy tailless rats if it's the tail they don't like. Tailless rats aren't actually very healthy, but once they realize how much they cost and how much research you've done to discover tailless rats they may down and buy you a $3 rat from Petco [which are fine - most of mine came from Petco.. even my Dumbo Archimedes. Just be sure to pick the most active, fattest one with clear eyes and no gunk around their nose - and NO squeaky noises!].
~They also come in hairless, dwarf, rex [curly], and hundreds of colors.
- Different varieties.
Umm.. what else?
~They give kisses! They need love! That's not a convincing argument.
~OH! Rats NEVER BITE. I have NEVER been bitten by a rat. I had a retarded rat who was horribly physically abused almost to death by people before I got him and he never bit me. He was actually a big sweety, and loved to lick my fingers. Like dogs; even after being abused they still trust people.
~They make a product that deodorizes their urine. It's called Bi-Odor, and you put it in their water. One squirt does the trick. Just be sure you clean out the bottle really good once a week on cage cleaning day. It gets yucky after a while.
~"C'mon mom! Rats are sweet, loving animals! Fine then, I want a cat." is what won my mom over. She's allergic to cats, but I didn't know that at the time. She knew I was likely to come home with a kitty... but it might not work with you.
Find weakness, exploit.
P.s. If it comes down to it don't get a dwarf hamster... they bite @[email protected]
I'm not a fan of hamsters... spawn of satan.... Gerbils, mice, and even some teddybear hamsters are ok. Don't get a dwarf hamster. Hope I helped!
