Rats grind their teeth for two reasons:
First, a rat’s teeth never stop growing; they keep the length under control by constantly grinding their teeth and gnawing on hard objects (this is why your rat may keep you awake at night chewing on the bars of his cage). Second, rats often grind their teeth when they’re happy! It’s called “bruxing.” You may also notice their eyes bugging out while they do this…it’s called “eye boggling,” and if you’d like to see a video of this phenomenon, click here!
the reason your rat is grinding it’s teeth is because, a rats teeth can keep growing and growing theres no end to it. So, what I reccomend is a teething hut… we got one for my rats and basically what it is is a small hut that smells like cinnamon and you just put in thier cage and they teeth on it.
I REALLY WANT RATS!!! My mom said I could get guinea pigs but now says she’s allergic. So I am going to ask her for rats and she did say I could get something small! Rats aren’t too small though so that’s good!
