I think the strangest would be Sea Horses. Some other not so strange but also not completely common are Sugar Gliders which I still have and 2 ducks that were kept in my house......they swam in my one bath tub that we never used in the guest bathroom.....I miss them!
Our ducks we had. We did not color them!!! I don't know how they were colored or anything like that and I had no control over it whatsoever. The orange one was mine and his name was Crackers and the green one was my husbands and I can't for the life of me think of his name! We got them for Easter a few years ago but I had to find them new homes. I want to eventually get more ducks though, I loved them so much!!!!
I use to have rats, they are the cutest things ever!! Theya re like dogs really. Well the ones I had were anyway... I miss them soo much. My first ones name was bella and she dies of some unknown disease. And my second rat was emma, she died of old age, she was 5. First she went blind, then she got a hunch back then she went deaf. Poor emmy and bella.
I use to own mice as well, but they got boring.
I use to have an axolotal (mexican walking fish) I had a few actually. They are pretty cool and weird looking.
We had a wallaby, she was a rescue. But we released her about a week ago. She has come back a few times since though! So cute!
We had a miniature pig who came inside. He could sit as well. But we sold him cause he didnt get along with the goats haha!
Silk worms, we had them too.
Hermit crabs, they were boring
Yabbies (red/blue claw creyfish), they arnt very stnge though
Im sure we have had more weird and wonderful animals, I just can't think of them haha. I loved my rats, they were awesome. Its such a shame they don't live very long :'( you get so attached to them
Hmm I had a crawfish named charlie kept him for 6 months! Also a possum named susie she was hilarious to watch eat spaghetti hold the noodles in her (hands) paws take a bite the noodle would fall..she'd start all over again lol. Anyhow that's my strange 2
