WELCOME!!!
http://www.rabbit.org is one of my favorites. Check out the diet section there as they will be a great help with young bunnies and as they progress.
It will include the type of hay, pellets and when to introduce greens as well.
A young bunny’s digestive systems is very sensitive so whereever you get him from, get the food they were giving too, and if you want to change to a healthier mix, be sure mix slowly over a months time until the old has been weaned out.
You want to be sure you don’t allow too much freedom too fast during littertraining. Hopefully, you have a pen so you can allow him exercise but limit his freedom. Otherwise he may “claim” the whole place. You will be getting him right at the challenging age as his hormones may start raging, so Snickers might be in for some unwanted action. Be careful with this, and if this happens, and she’s not havin’ it, then you may need to wait until he’s neutered before you try and bond them.
Can’t wait to see him.
Show us pictures when you get a chance.
