I think I've been pretty lucky with my bunnies. Cinnabun (male) was neutered at about 7 months of age (13 years ago!). He started getting territorial about his cage once he matured, and that actually didn't cease until he was about 5 years old! He also bit occasionally once he wasn't a baby anymore, but overall he was a complete joy. He never sprayed urine or humped or anything and was actually completely litter trained from the time we got him. I think my experience was a bit atypical because he was very skittish for the first several months he was with us, it wasn't until he was an adult that he loved being held and given attention.
Rory was neutered when he was about seven months old too, two weeks after we got him from the animal shelter. Like Cinnabun, Rory was magically already litter trained. He also didn't hump or spray urine and also has never been territorial about anything. He's a little bit reserved, but will lie on his back in my arms and likes to be petted and kissed. I didn't know him as a baby, but since he was so nice before and after being neutered (and he's still in his teen years I guess since he's a little over a year old), I can imagine he was very sweet baby.
Tallulah was an incredibly sweet baby. She liked being held and would lie on her back on my lap, follow me around and sought me out for attention and pets. Sometimes she wouldn't leave me alone! It was pretty funny because on the DAY she turned 6 months old, she bit me for the first time because I stopped petting her. She bit me lightly every day for about a week when I'd feed her, but then she stopped and never bit for the last month of her life. I think she figured out that she'd have to wait longer to be fed (only 10 minutes or so, but a lifetime for her I'm sure) if she bit! She started marking around Rory's cage with poop and started chinning things. She also stopped wanting to be held or cuddled as much. It didn't hurt my feelings too much though because we were closely bonded anyway and I knew it was because of her hormones. We were going to have her spayed shortly after she died (she had been sick most of her life so I wanted to wait longer before spaying her, she even had an appointment 3 weeks before she died but I canceled it because I wanted to wait longer). It would have been interesting to see if she would have been better with her litter box or stopped chinning things after she was spayed, and if she would have liked cuddling again.
Sky is now 7 1/2 months old and like the other boys, never humped or marked or sprayed. He was neutered almost 3 months ago and still isn't very good with his litter box, but has gotten much better! He's super sweet and his personality doesn't seem to have changed really.
Sorry this is so long! I just wanted to share about all my bunnies. Basically, I wouldn't worry too much about Liffy's personality changing. I thought I would be sad if Tallulah stopped being as cuddly, but when it happened I wasn't too much. I knew she still loved me just as much as before, and she was still bonded to me. For example, we left her with a friend for a weekend when we went to get Skyler, and she refused to come out of her cage the whole time! When I dropped her off and when I came back, she was excited to come out of her cage there and play in the living room. Also, if Liffy does get moodier, she might go back to being cuddly once she's older. Cinnabun was incredibly loving and cuddly after the age of 4 or 5, much more so than when he was younger actually.
Sheesh, sorry again for it being long! I just love your Liffy girl, she's so adorable. You should share more pictures! :biggrin2:
