The Glee actress and her wife Lara Embry were forced to say goodbye to their beloved pet, and Jane took to Twitter to share the news of her passing on Sunday.
'My sweet kitty Greta took her leave from us. We loved her so. Kiss your own kitties and pups right now,' she wrote alongside a picture of Lara with the cute cat.
'Thank you so much for your most comforting words about sweet Greta kitty,' she added later. 'Boy, they get into our hearts. My grief though painful, is clean.'
Meanwhile the cat-loving couple still have Lhaso apso Olivia, Wheaten terrier Georgie, and tabby cat Riley to care for.
