I have a 1 year old cavy that started standing up in his cage, biting the bars(as if he wanted out) and doing back flip type jumps (not popcorning) like he really wanted out of the cage now. He was fine before he came out of his cage for "lap Time" but after putting him back in 2 hours later, he seemed anxious and afraid (as if he saw a ghost). He has never done this before. The only events that took place while he was out were his cage was cleaned ( no cleaning products are used) and he ate part of a pretzel (no salt). When I approached his cage and opened the door, he climbed on the door and into my arms burying his head into the fold of my upper and lower arm (he usually avoids). He also would "talk" in a low rhythmic pattern as if he was afraid of something in his cage. Any suggestions? He lives by himself and is in the living room and I was watching TV when this took place. He would not eat the lettuce in his cage, but when he sat on the couch with me he would eat and purr (normal Happy). Could he be getting too much attention? Is he spoiled? Is he in rut? I can not find any info on this type of behavior. I see no ear mites and he looks to be in otherwise good health. Thanks for your help in advance.

Is there any one else that plays with him or anything. Maybe there was a loud noise or something that bothered him while he was in his cage. Has it accideltly been knocked on the floor or anything? I own 4 chinchillas. And when they are scared they emit a barking noise and get very upset in their cages but are fine when taken out. But since you mentioned the eating thing... maybe he's having bladder problems or something. I wish I could help more

Well I had a dwarf hamster and gerbils and they always did that. I always believed it was because I did not take them out of their cages enuf but I had 12 gerbils and 1 dwarf hamster and I did not have a lot of time to spend with them. Sometimes they would do that to get my attention and they would show me if they did not have food or water. But I think it just wants more attention that's all.

I think it means your guinea pig wants attention... sometimes my guinea pig does that because I think he's lonely (his companion recently died) Your guinea seems to love spending time with you and this is probably why he's doing that.
