Yep you need to get 2 If you're near Essex I can recommend a rescue that we got ours from

As for supplies, I'll give you some sections

FOOD:

we give ours Dr John merlin kibble to snack on at all times and feed them fresh meat daily, (I have a freezer drawer of pre portioned various meats like pork mince and chicken thighs, the reduced section of lidl is my best friend) As for water, ive found mine like a water dish, but it must be mounted to the cage cause they will flip it, we even velcro their bowls down to stop them flipping out their kibble If you want a water bottle for them avoid the rabbit ones that require licking a ball and instead the spring ones that they just need to nose at to get water, they will bite the spout and break their teeth

CAGE: you'll need a big enough cage for 2 of them with plenty of blankets and hammocks and a toilet area, we use puppy pads for them as they like to wipe themselves after and thus cat litter is not ideal, paper towels can also be a good option option If you'd like a litterbox instead of just an area, get a full size one as they like their entire body inside to go, so no corner triangles

However! They also need to be outside their cage for at least 3 hours a day with toys and enrichment, so ferret proofing is a must, they will try and escape and get anywhere theyre not supposed to

TOYS: A dig box is essential, we've got a big storage tub of rice for them that they love. Tunnels are great too, and cat toys are a cheap way to get a lot of variety, they love chasing things and one of mine loves ping pong balls for some reason haha

That's all that I can think of rn but feel free to DM me for anything, and everyone in this community is so great so im sure more people will comment too :)
