Helene, thanks for the update. I'm so glad to hear that Button's surgery went well and now I hope that she'll recover quickly and start feeling much better. If the cancer spot was in her eye then it's a good thing that it had to be removed.
Your a wonderful cat mom and I'm sure that she'll thrive in your care. She may even turn into a more loving cat and be much less grumpy. I'm still sending lots of prayers and positive thoughts her way. Please take care. (((HUGS)))
