I don't know what to do about my grieving cat
(Eau Claire, Wisconsin US)
I have a 9-year-old DSH female. Her 15-year-old companion (male) who was diabetic passed away at home just 6 days ago on 05/26/2020.
She has been isolating herself since her companion passed away. She is mostly just laying on the comforter that her companion always slept on.
I am concerned about her now being the only cat in the house and that she is and will be lonely. She has never been without a friend.
Should I adopt a companion for her? I am willing to do anything for her. I would be greatly thankful for any advice. Thank you so much.
