I'm dealing with an aging pet right now, too. Besides my two sibes I have a cat who is about 17. Poor guy, this has been a rough year. he's lost half his body weight, and most of the fur on one side of his body has fallen out. He's been to the vets, got tests, and his kidneys are sluggish, so we give him fluids under the skin every few days to help his kidneys flush. it breaks my heart, he's been such a wonderful part of my life for thepast 17 years! I'm just loving him every day he's here and trying to make sure he's comfortable and safe. It will feel so weird when he's gone....
Star is 8 1/2, and I see changes in her face, she aged alot last year after our Rosie was killed by a car. Till then Star still acted like a puppy. (we've had her since she was 5 weeks old) She's much slower and quieter now. I'm hoping she still has another 7 or 8 years left, God willing. I love all my furbabies sooooo much.
