My mom's cat needs an emergency vet visit...

Hey, this is Ester my mother's last remaining family cat and the cat I personally delivered to my mom in my pocket as a kitten when I was in my late teenage years. She is a sweet and loving cat that has so much love to give and has been the solid rock of my mom's house for almost twenty years now... Unfortunately she has a compaction condition causing her massive weight loss and intestinal fecal compaction, even with the proper diet and food. She needs an emergency vet surgery to get rid of this serious issue. We really don't want my mom to lose her final cat unless it's absolutely necessary.

Anything helps even small amounts...
