The cats are ALMOST fully tolerating one another! It has been a VERY long battle. Molly was very much my cat when Marbles came home. She immediately hated him and we just raised him separately from her. The house has always been split in half. We've made a few attempts to get them together but had only gotten so far with it and I've never felt comfortable enough with the progress to let them try and exist together without being bound in velcro.

Molly spends the night up here and we swap them in the morning. Molly runs down the stairs then when she's at the bottom I plop him down and he runs up. Recently I've started holding dragon like burger up to her on her way down so they can sniff one another fully without actually touching (minus some gentle boops). Every day we take a few moments longer together. This has made more difference than anything else we've ever tried. I'm excited!
