We've had our cat, Dory, for 18 wonderful years.
She has had a great run but I'm afraid the end is near. I asked Alexa what the symptoms were of kidney failure in cats and basically everything Alexa said (loss of appetite, weight loss, using the bathroom in unusual places, excessive thirst, lethargic), my cat has. She has also lost a lot of fur on her tail. When I change her kitty litter, it's barely used. It's so sad.
I feel like if I let her go on her own terms she may be suffering and that would be selfish on my part. On the other hand, putting her to sleep would end this but she may just not be feeling well and will feel better in a day or two.
I love you, Dory.
