Six, because the question didn't mention someone taking their body out of the cage.
it depends on the size of the cage.
1+2+4+8=15 There can't be half of a hamster. Start with the smallest cage with the smallest amount possible:1
Many people who have owned hamsters say that, that kind of cage is dangerous for hamsters, even dwarf hamsters. Also, there are many ways that a hamster can be killed in that cage. It's a death trap for a hamster or anything else. They may look cute and colorful but they are NOT good for any type of small rodent.
It is recommended to have only one hamster per cage to prevent territorial disputes and fighting. Hamsters are solitary animals that prefer to live alone, so it is best to provide each hamster with their own space and resources in their cage.
Just one. (1)
two per cage for dwarf hamsters but for other types one peer cage ask at the pet shop just in case though
You can keep a maximum of two dwarf hamsters in one cage to prevent territorial issues and ensure they have enough space to move around comfortably. It's important to provide plenty of hiding spots, toys, and multiple food and water sources to reduce competition and stress among the hamsters. Regular monitoring of their behavior and health is essential when housing multiple hamsters together.
Cotton is most likely ok, for many products used for hamsters are made of cotton.
Its impossible to count because every for secs a hamster dies and a new one is born
A glass aquarium or a wire cage with narrow bar spacing (less than 1/4 inch) is best for Roborovski dwarf hamsters to prevent escapes. Make sure the cage provides ample space for digging and burrowing, as well as multiple levels for exercise and enrichment. Avoid cages with plastic components that the hamsters can chew on and potentially ingest.
If you mean without a room mate, it is more then not cruel. Actually, it would be slightly cruel to put 2 hamsters together, if one or both isn't young. Unless you have a huge cage. If you mean abandoning a hamster, yes. For hamsters had been domesticated to humans for many, many, many generations and aren't used to being back in the wild again. They can't get food or water by themselves, either. Not when they're locked in a cage, THAT'S for sure! Not just for Russian hamsters, all hamsters! Not just for that other answer, but both answers.
Yes, don't worry, this was the right thing to do. I have bred hamsters many times and I know that after about 2-3 days of giving birth the female will let you clean the cage and pick up the hamsters etc. They are less protective than guinea pigs which will reject their babies if they have a human smell on them. But, just watch the babies to be sure.
