Well my little one that i went through similar with, she was considered the runt of the litter. She had a hole in her heart. She was small but as fierce as a lion. Her heart was bigger than most, if anyone was in pain or having a bad day she would find them and make them let her sit on them to give comfort. I often woke up with her and her sister draped around my head.
She loved the outdoors when she was younger, used to disappear for days on end, bringing back live birds and mice on occasion. Always so proud. Few other cats were allowed in her territory, those that were accepted were as kind and gentle as she was.
As she got older she became more of a house cat that loved cuddling up and sleeping with her hoomans!
She became my constant companion, anywhere I went she went with me. I used to wait for her to sleep before leaving the house. She was a wonderful, little teddy bear or cuddle blanket for anyone that needed it.
I miss her everyday, thoughts and memories of her bring comfort even now. Some of my best memories are sitting with her and her sister on a quiet evening.
