Hi Oodelally, welcome here.

Firstly, thanks for adopting 2 needy buns! It’s unbelievable isn’t it, that people just let them go into the world on their own?!  Chances are Ringo is a lovable mutt with some Silver in him but never mind that, most of us here have mutts! The Silver is said to get between 4-7 pounds. With the fur changing, it could be he’s beginning a molt. My bunny gets whiter tip ends as she begins hers. When molting, you often see a line moving from the head onwards. It’s pretty interesting to see.

Another member here that has some Silver Fox rabbits (different breed) said sometimes if she feeds them sunflower seeds, the oil triggers a molt and the silvering falls out! So diet can certainly affect their coats.

On you last question I would say; rabbits come to like and trust you in their own good time! One of the best things is to just be down at their level and let them approach you. Just do anything, read the paper, a book, whatever, and pretty much ignore them. They usually cannot resist and come to investigate you. Don’t immediately reach out to pet them though. If they bump you with the nose or lower the head to the ground, you can take that as a “pet me” request. It does take some time and being shelter buns, they may have some trust issues to work out but it’ll come!

Oh, by the way, some piccies will help identifying Ringo a bit……..and don’t leave out Edsel!  I’m really requesting them so I can ooh and ahh!

welcome here! i agree, i think pics are in order. even if we cannot identify your bun, we want to see pics… just b/c we love bunny pics!

Congratulations on adopting these 2 rabbits.

As for the breeds, a rex rabbits is pretty easy to identify based on the fur but most shelters and rescues aren’t truly familiar with rabbit breeds so it’s possible the Silver rabbit is something else or just a mix.

I agree with Jerseygirl on the trust issue and do post some pictures of your rabbits – we love pictures.

Congrats!! We need pictures!!

Rabbits do change color especially when they are ‘molting’ or shedding. They don’t change seasonally but when they go through a heavy shed, its quite normal to see some color change.

On picking them up or handling them-really you just have to work at it; It takes a lot of time to earn a bunnies trust. Once you do-it’s very rewarding. The treat thing is great. Try sitting on the ground when your reading or watching TV, they’ll come right up to you. The other thing I do is grab a sleeping bag (ok I’m a nerd!) and take a nap on the ground, so they’ll come hang out with me. Being on the ground is the best way to interact and the more interaction you have that’s postive, the more they’ll trust you.

Silver; I don’t think I’ve ever heard of it before *off to look it up* From what I see sounds about right. Looks like they are a solid color with white frosting (like a ‘roan’ in horses) http://www.albc-usa.org/cpl/silver.html
and rabbits are pretty much the cutest animal alive and people still manage to do terrible things to them, so yes, I’d believe someone would dump a rare breed -Your luck though

Welcome!!
