Hi Nutlilly, welcome to BB.
Would love to see pictures of your bunny girls sometime.
Lilly is cute but shy also and does this loud noise thing when you pet her. I don’t know if its her screaming in fear or purring. She isn’t fixed yet. But will when we get the money.
These 2 sounds are very different. I think you’d know the scream if you heard it. It would probably send chills up your spine.
The purr rabbits do is just clicking their teeth together quietly. Mine seem to do 3 clicks-pause-3 clicks and so on.
Is the sound Liily does more like a squwaking perhaps?
When I bought my rabbit Maple home she did very loud noises like that whenever I approached or touched her. It turned out she was pregnant. She stopped doing it after she had the babies. So it was due to hormones & fear.
How long have you had Lilly? Longer then a month? I’m just wondering about the possibility if pregnancy (or even false pregnancy).
That aside, she could just be a very vocal rabbit. Some are. : )
