Sorry I have only just seen your post Amethyst and I am so very sorry for your loss of Pumpkin
Its never easy when we lose them but when they have that much energy the home is even more quiet so you miss them more
The plant pot is a great idea and the perfect way to bury him and to remember him by. You are still in shock and going through so much right now that no wonder you feel miserable
I know it will be hard but by cleaning his cage and putting it away for now it will give you a chance to say goodbye to him and might help a little. ((((((((((( HUGE HUGS ))))))))))) to you and I hope you start to feel a bit better soon. Rest in peace sweet little Pumpkin xxx
