I'm sorry, but also glad, to hear I'm not alone.
We've known for a long time that I am Sky's bonded friend and if I'm out the room when he expects me to be there he will sit and wait as close as possible to the door. When I was in hospital back in March he was clearly moping and needed his first ever dental shortly after.
During November I didn't sleep in my room for a while because I was bonding someone elses bunnies, and right at the start of December he just crashed hard and fast and we had to take a 2 hours 'dash' to the vets in the snow, where he was admitted for a dental and hefty pain relief (what I had at home was not touching him). We've been battling to bring him through ever since. Its been a total nightmare. He is just about getting to a better place now, but not anywhere like where he was. He will now sit in his litter tray and eat if I'm not in the room. Before he just sat, he wouldn't get up and drink, nor eat hay, would just sit, and also eat his fecals (we could tell by the lack of evidence of movement, etc).
i love him so much but he has been a huge stress, lol. Of course, when he wasn't here I had my own separation anxiety :lol: He has to live forever.
