Poor little girl kept getting behind and under the fridge, i was scared to death, so I took a piece of wood that is used for blocking the sliding door from opening and put that between the wall and the fridge... It was just a little bit too small of a gap so that she could get her head stuck but not out... and she didn't make a noise so neither my fiance or I could help her and she passed away :'( God if I had just let her go back there or gotten foam in between it instead of the wood... our poor little Elsa-Bear is VERY VERY greatly missed by me and my fiance as well as her 6-months companion, our 4 1/2 year old Malina-Bear. A very VERY important lesson about young ferrets that love to dig into everything and get everywhere, make sure they are safe and every crack is ferret-proofed....I will NEVER EVER make that mistake again.. R.I.P Elsa-Bear, I hope you've dug up every single flower in heaven by now <33
