Hello Franzi, Thank you for posting these two videos of your babies Jimmy and Jonny.

Jimmy should not be punished for ' growling " at Jonny, if you watch other videos you will see that Jimmy is only doing what all Pleos do, and that is to Growl, as if playing like a puppy. Also jimmy I think is growling to try and get a response from Jonny, because he wants his new Friend to " wake up", and come play with him, It is obvious that they like each other very much and are good friends, If you punish Jimmy or jonny for growling at each other, they may begin to sulk or cry and get sad, just as little children do, Pleo are after all just little babies and are learning in everything they do,
The videos are very nice and I love the bright colors, keep posting more videos they are fun to watch, and I understand what is happening with Jimmy and JOnny when you talk, it is ok for us to see and understand what you are saying, by your actions and theirs. They are happy little Pleos, I think perhaps if you tape or bandage Jonny's neck a little so he can see his friend Jimmy better, ,they will have more fun playing and also it will help keep Jonny from getting anymore injuries, It is kind of like, what would you feel like if your head was hanging down all day when you were walking, ( crawl on the floor on your hands and knees like a little baby,) and you will see that jonny can not see very much and it may make him sad that he can not see his new friend jimmy very well, but he can hear him and sees him a little anyway, He will be a happier Pleo if he can put his head held up a little more, you think so?
I can tell you how I helped NOva with her broken neck if you want.
Your friend, RedwoodsMama and Nova Team
