That's great!! I'm sure he'll find a great home thanks to you.
And you are welcome! I love being able to help people and share rabbit info. I could talk about rabbits all day!
Look up the house rabbit society. Check to see if they have a rescue near you.
Most rabbit rescues will spay and neuter and find a great home for their rabbits. They won't let rabbits go home to people that want a new toy for their kids, or people that are just going to out them in a tiny cage...
Are you planning on keeping him/her if you cannot find the owner?
It's likely that s/he was dumped. Could be from easter.
I would take him/her to a vet for a checkup and they can tell you if its male or female.
If that is not an option check the ears or any mites or other critters, be sure...
