my flemish giant, who is 5 months old now at 24 pounds makes weird noises. it sounds "nasally" but she does not have pasterella or any infections. she doesn't seem scared or worried and she seems to do it just out pure joy. she will even do this when she binkys. i have 5 other rabbits and i've never had a rabbit that is so vocal. she won't thump when she is mad either, she just makes this really loud "i'm annoyed" groan and hops away flicking her feet. she is not overweight, and gets a good course of pellets, veggies, and unlimited hay. she seems to be a really happy rabbit other wise. the sound sometimes sounds like she is farting. and sometimes when guests are over they think my flemish is passing gas infront of them. LOL! is loud vocalizing rabbits normal??? or should i be concerned something is wrong with her?
