@pup_hime it took sasha years before she started doing it. It began with her just hanging out with me while i sat at my computer through each day
Eventually she would just want to hang out with me when i went away for bed too. Id hear her yowling for me downstairs wondering where i went amd then shed find me in the bed and settle in all purring and such
I think if you give marty a space to hang out with you during the day he might end up the same way after some time
