In my opinion, and I have a lot of trainging and dog experience, she does not want to play with it at this time, so she is carrying it around in search of a safe place to "bury it" so to speak and she cannot find the place she wants to put it.
I have had dogs do this in the past.
This does sound more like a girlie-thing, yes. My dog sometimes carries her squeaky toy around, and carries it to bed, and cuddles it. It's a mother instinct thing. I'd think it's rare for a male dog to do this? Perhaps the bunny (and reindeer) are like 'security-blanket' objects for him? Perhaps when he was in the pound, this toy was his security, a familiar thing for him. And he's going back to that feeling for some reason.
It's interesting that in a wolf-pack, most all of the pack members (I think including some of the males) are involved in care of the pups, and are protective towards them.
Whoops, I meant to say maybe your dog thinks it's his puppy not kitten. Sorry! I had just been on the Cat forum and got it mixed up!
Have you talked to your vet about this?
My cat does that with my husband's rolled up socks. It drives my husband crazy! He finds socks all over the house, lol. She's been doing this since we adopted her from the pound. I always wondered if she might have had a litter and she was treating his socks as if they were her kittens. She'll walk around with the socks in her mouth crying this mournful cry. Otherwise, she acts perfectly happy.
I'm surprised too, that your cat is a male because that's what I would have thought, too! That he was thinking his toy was his kitten or something.
I honestly don't know what else to think!
Wow. I'm surprised it's a he. Sounds to me like it's a she and is pregnant.
It seems that maybe the squeek itself is reminding him of soemthing and he's being very motherly and depressed with it.
Did you ask an animal behaviorist or your vet? Poor little man
