Why is my rat nipping through the bars?

yes this problem is quite common. your rat is just excited. Here is how to solve it: Spay a bit of bitter apple spray, or another training spray (i use time out) on your finger or on a glove that you wear while holding him (i reccomend a glove because if you get it on your hands, eating burgers or other hand food is a real bother.) This will work and always has.

well after reading all the other answers, i dont think any really are going to fix your problem.

is he acting aggressive or just nippy, there is a difference, is he hissing at you or anything. if not then i do not believe he is being territorial. if he was, he would be showing some sort of aggression (puffing up, or hissing).

maybe he is just over excited when you come by because he knows he will be getting attention or food. if this is the case,do not pay attention to him when he does it. keep reaffirming no when he does it, and do not open up the cage until he stops nibbling.

i hope this helps, its kind of hard to fix it when you dont know why he does it.

Hi. I have 12 rats now (lost one last night :() Ive only had one biter who was cage terraorial, she is fine now but with all my rats some will bite through the bars and some wont. With mine i think they think your offering them a treat and go to snatch, though ive never fed them through the bars. As general though there very loving ratties and give lots of love to us

Rats are social animals so maybe its ateention seeking, rats are best kept in groups with there own company also.

I read somewhere about a lady who had a nipping through the bars rat and she trained him to stop by constantly handing him boring little bits of cardboard through the cage bars. She said it took about 50 tries but it eventually worked and he stopped nipping. I'm sorry, I don't remember where I read it, and I can't take credit for the idea anyways! :0)

Rats are social creatures, and need to live in pairs or groups (same sex of course). I doubt this is the cause of his problem, as many rats do this - it's just one of those things. But he could really do with a pal or two, and with company he might not have as much spare/bored time to nip through the bars!

Edited to add - have you considered getting him neutered and introducing him to some girls once he's "safe"?

don't worry, usually all rodents nip at the bars if they have cages. He is probably just bored, so nipping at the cage passes time. Here are a list of toys u could get him. They can go right inside of the cage.

wheel (with ridges so his feet don't fall through)

a ball (not a regular one, u can get them at the pet store to put ur rat in and he runs in a ball throughout ur room or house)

wooden bird toys (they chew on them and play with them)

just take ur rat out to play more and will be less bored. Good luck!

there is absolutely nothing you can do about this whilst you continue to maintan that he is ok as a lone rat

NO hes not, his behaviour is telling you that, what he is doing is the same things as bears in poor zoos when theyre just pacing up and down, chimps when alone biting and pulling at themselves or birds when they pluck their feathers

he is bored and starved of affection from another of his own species and until he gets that he will continue with this OCD behaviour and aggression towards you his 'jailer'

he hates his cage and you putting him in there so much that he is 'punishing' you, hes telling you hes lonely in the only way possible, by showing that his behaviour improves outside his solitary jail and interacting with you.

but unless your going to interact with him 24/7 then you are just keeping him cruelly for your own benifit

get him neutered and then in 6 weeks get him a couple of girl kits around the 8 week old mark and watch him blossom OTHER THAN THAT rehome him to someone who will care enough to do so

but if your going to keep making excuses to enable you to keep him alone then whats the point of asking for advice and help?

with the net at your fingetips there is no excuse for ignorance

educate yourself and improve your rats lifestyle

i read the other answers, and i noticed someone suggested a salt lick. rats do not need a salt lick.

i suggest the link below and maybe you'll find some answers that you need.

He might be just nawing down his teeth. Alot of rodents will do this. Try to put a salt block that is made for rodents in there and see if this helps. Hope it works!

well i have 12 rats and nun bite me ever i guess you can hold him more mayb needs more attention and is not getting used to ppl
