Sometimes you just need a little time to detach yourself from their plight. It's hard to do, because rats can be very personable, so it's easy to get attached to some. But in the grand scheme of things, there are just so many rats out there. With their crazy reproduction rates and short lifespans, rats just cycle on and on. So when we meet a new rat, we're only seeing a small portion of waves and waves of rats. And the sad fact is that there are likely some really awesome ones out there that end up on the rotten side of luck; they get fed to snakes, they get sacrificed in labs, or they simply die in the wild. It sucks, and now I managed to depress myself.
But because of the high mortality of rats and the statistical impossibility that we can save them all, we have to turn our focus to the rats that we can care for. I have three lovely rats who will never be fed to animals, experimented on, or left to their own devices in the wild. I spoil them, and I'll keep doing that until they reach the end of their lives.
And we need to balance their current needs with the future. It's tempting to take on more rats, but new rats will take up space, money, and attention. As such, we need to be discriminatory in our selection. I almost got a fourth rat. We were at a pet store the other day and found the friendliest rat ever. Well, not as friendly as our, but for a rat who spends her time in the back room, this one was really friendly. We were tempted to get her, but we remembered that the three we have take up plenty of time. That fourth rat has to be special. In the end, my wife rejected her because she was a) larger than our current rats so we weren't sure how they would get along and b) not a Dumbo rat. Personally, I was willing to overlook those obstacles for this rat, but this is something we both have to agree on, so we ended up not buying her. I still think about that rat. She was included with the feeders if you can believe that. I told the employee that this rat was so sweet that she should absolutely be a display rat. She could sway any newcomer who was on the fence about owning a rat (though such a newcomer would likely only purchase the rat singly, which would be unfortunate).
So yeah, all that just to say that you sometimes have to stand your ground and say no. But you know, be open for that rat that wins you over. We're still waiting for that fourth rat to win both of us over.
