How to tell when a rabbit is comfortable? Teeth grinding/purring question.?

Your bunny is actually a cat! On a serious note, teeth grinding can be a sign that your bunny is happy and content. On the other hand if the grinding sound is unusually loud it could be a sign that your bunny is in pain or distress, but it sounds as if your bunny is happy.

So nothing to worry about, You are doing a great job as a bunny parent! You could have him/her a health check if you are worried that it could be due to illness. Check eyes are clear and bright, nose is clean, no lumps or bumps, teeth are short, claws are short, no cuts/grazes, no missing fur patches etc.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
