how adorable! The poor little things losing their mum I can't believe someone would do something so evil are you still looking for mum or has it been too long now?
Still looking however, I honestly think its been to long and starting to come to terms we are not going to find her, the park/green is only a step out of my back gate though so we are still looking everyday, several times a day. also if i look out of my upstairs window i can see over most of the park so find myself doing that loads, and peeking in the garden, its became a habit now. She has definitely moved from the area she was so making it harder to search and less likely she'll return
I hope the little ones are doing well, they definitely look healthy and happy in the photos
