How can I get my male and female hamsters to live together safely?

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 a very common mistake to take two hamsters and put them in the same cage, regardless of their gender, they will almost certainly fight and you will either have to eventually separate them to two different cages or you will end up with a dead hamster. i strongly recommend NOT putting two hamsters in the same 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!

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. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Thank you for your question. Unfortunately if the hamsters were not raised together, it is not likely that they will get along and very possible they will fight and injure eachother. I would be nervous that you are not able to watch them at all times and they could fight and hurt one-another. https://www.petco.com/content/petco/PetcoStore/en_US/pet-services/resource-center/caresheets/dwarf-hamster.html

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!
