I frequently find our senior cats enjoying the warmth of the strengthening sun on their old bones. The upstairs patio window faces south and you can tell by the collection of cat beds in front of it that this is a favorite spot.
I really don't know how old Grendel is. She was a full-grown cat the summer Bunny was born (1996) so she is at least thriteen and more likely fourteen or older. She lived feral in the woods and I caught her in 1996 but she escaped after we got her spayed. I didn't see her again for several years until she turned up in our cat trap in 1999. Until then, I thought she must have met some unhappy end, so finding her alive was like getting a second chance. For her and for us.
So she has been in the house now for nine years. She doesn't trust us but we can handle her enough to take her to the vet for check-ups and such.
The new girl Jasmine lost no time in figuring out the best places to nap.
