We lost our wonderful dog last month. We’re heartbroken. She was 14 and we had her since she was a puppy. We also have a cat who is three, and we’ve had her since she was a kitten.
The cat liked the dog, but it was unrequited love. I think the pooch was just too old and world-weary to be bothered with a mewling little kitten so stuck to (usually) civil exchanges.
Now, the dog is no longer with us and the cat seems to be lonely. They never cuddled up together (the cat tried) or really interacted much, but I think she knows her roommate is gone.
Typically, the cat isn’t that active during the day and always finds a sunny patch upstairs to chill in. But then in the evening, she’d sit with the rest of the family (inc. doggy). She’s not doing that now.
At nighttime, we’d normally have to keep the door to our bedroom closed because the cat would come in and try to play with the dog (who spent every night of her life asleep next to our bed 
) and generally get hyper, but now she comes in and either lies on the dog’s bed, or on my foot.
She’s eating and drinking and toilet if as normal, but she just seems very glum and definitely less playful than usual.
We will get another dog at some stage, but not for a while; it’s just too soon. We’re also going to be moving house shortly so don’t want to add another cat just yet.
Any advice?
Is it possible that she’s pining for the dog, although they weren’t close? Is there anything I can do to help her?
She had her vaccinations and a check-up about six weeks ago and appears healthy and allergy so I think she’s medically fine.
