Will two male Roborovski dwarf hamsters get along in one cage?

There is a good chance that 2 adult male hamsters will fight and induce significant injuries. If you would like to try to introduce them to each other regardless, I would start with a completely clean cage with fresh bedding and keep them on either side of a mesh divider so that they can see and smell each other without being able to fight. I do not recommend putting one into the other’s cage as the original hamster will likely become extremely territorial. For 2 weeks or so, you can remove the mesh divider for short periods of time while you are carefully monitoring them and offering plenty of enrichment in the form of shelters, toys, food treats to keep them occupied. If you notice any aggression, I would give up and keep them separate from then on. If after several supervised periods alone (about 30 min each time) over 2 week you do not notice any signs of aggression, you may remove the mesh divider but examine them carefully each day for scabs/wounds especially on the rumps, genital area, hind legs. Good luck! They are very cute!

There are certain hamsters that will tolerate one another, but in general, they are solitary. The safest option would be to have two cages for the hamsters. This would be especially important in case there is a male and a female or two males. I hope that this gives you a place to start!

If your hamsters initially did not get along I probably would not try to put them back together again. Also, if you cage an male and female together they will mate and you may have many liters of babies to take care of. You may be able to get them together on ‘neutral ground’, somewhere outside of either of their cages so they won’t feel territorial of the space. I hope this helps.

It depends on the hamesters. Not all hamsters will get along. It is also important that you do not put male and female together unless you want babies or one is spayed/neutered. If you are going to try you need to monitor them closely and I would not leave them together over night. If they are doing well you can leave them together for longer periods of time. Some hamsters will have aggression when put together. Hope that helps

Hello and thank you for reaching out to PetCoach. These are very good questions and it is thoughtful of you to ask these prior to obtaining a hamster. I've attached a link that is very helpful in explaining certain hamsters that live well together and special care instructions. I hope this is helpful! https://www.omlet.co.uk/guide/hamsters/getting_a_hamster/keeping_more_than_one

It's most definitely due to fighting, they are known to be fighting when kept together, for this reason it is recommended to have only one hamster per cage. unfortunately many pet shops tend to give false information about this, they don't warn you about this issue but this the unfortunate truth. i recommend separating them into 2 different cages.

Unfortunately yes, it can be very common for hamsters that are housed together to start fighting. This can occur even if the hamsters have always been together. I would recommend keeping them separated for a couple days and then trying to re-introduce them again like you did last night. Hopefully they will be able to get along with each other in the long run. If not, to keep them safe, you'll have to keep them separated. I hope this helps.
