Sue...It's been so hard to read these posts about Killian. Now that he has turned the corner I am breathing a little easier. My Ashley went to the Rainbow Bridge after her liver became enlarged. One day she just stopped eating. When she tried to eat it came right up. She went down hill terribly quickly and spent the last 5 days of her life in the vet's hospital on IV trying to fight off whatever was damaging her liver. A biopsy was mentioned as a possibility but at her age of 14 it was decided against. Now that Killian has turned the corner I feel that some of my most worrisome fears can be put to rest. I have read each and every post and held my breath through bad news and good news and am so, so happy that he is eating and playing. God bless you Killian!! Continue to feel well and keep on improving!! Lots of love to you and your mom.
