Curious about Ferrets

As stated before, all animals can bite. But ferrets are on the low end of the bite list IMO. I have only been bit a few times by a deaf ferret I rescued from a abusive home.
They sometimes do bite if they are very excited in the middle of play, bare in mind that a ferret's skin if pretty thick, so when they bite eachother during play it does not hurt them but it might hurt you. Though they can learn pretty quickly to not do that to you.
They are also very easy to litter train. Ferrets almost always have to use the bathroom (and they pee and poop at the same time) when they wake up, so put them in the litter box when they wake up and do not let the leave it until they use it. Do that a few times and they get trained very fast. And ferrets like to poop in corners, so make sure to put the litter box in a corner.
Also the do need to be let out at least 2 hours a day. And you can even get them a harness to play outside, but watch them as they can slip out and ferrets cannot find their way back.
Get at least 2 of them, they do like to have friends. You can get males and females however more than one female is more likely to fight with eachother than 2 males. With ferrets females are the leaders and if you get a female and male the female will beat him up a little but should not injure him, just slap him around a bit. lol
Do your research on food brands, alot of ferret food is actually bad for them. And you can spend a little more on the good stuff for ferrets because ferrets eat alot slower than most pets so a 25 pound bag can last 2 ferrets at the very least 6 months.
Also you should not give them toys made of rubber or foam, they like to chew and swallow things and those will get stuck in them.
And because this would be your first time owning ferrets I would recommend a older one, one at least 4 years old. They are much more calm and easier to watch when they bounce around the house doing the "weasel war dance". lol
As for grooming they rarely need baths, in fact too much bathing will cause their skin to become dry and flakey and they will start to smell more. They need their nails clipped and their ears cleaned (BTW their ear wax is red, so it is not blood you are seeing.).
And most ferrets are already spayed and neutered when you get them at a petstore or shelter. I do not recommend getting a unaltered ferret. intact males are very mean and smell horrid. And intact females can actually die of infection if not spayed or mated.
Hmmm, what am I forgetting? lol
Is there anything else you want to know?
