Okay slightly uneasing topic open and read if you want

Andy - 1.5 years old from a heart condition called core triatriatum sinister. All of a sudden around Christmas he started having attacks like asthma attacks, and or vet at home did some xrays and discovered pectus excavatum, so we took him to a cardiologist at the university in January. He did an ultrasound and echocardiogram and discovered that he actually had a tissue membrane bisecting his upper left chamber in his heart, so the blood was flowing through a opening 1/16 of an inch wide, rather than flowing through the entire chamber, and his blood was not oxygenating as a result (hence the asthma like symptoms). He told us the condition had never been corrected before and he had less than a month to live. The vet offered to try a brand new technique never attempted before, and after long hours of trying to decide what was best, we went with the surgery. The surgery itself was a success, but it took too long and Andy didn't wake up. At least Andy will be helping other cats in the future. [If anyone ever comes across a cat with core triatriatum sinister PM me, I'll give you the name of the cardiologist who did the surgery.]

Hera - indoor environmental poison or electrical shock, age 6 months
(Bang, yelp, Hera dashed out from under the stove, was seriously ill, went to vet, stabilized on oxygen, no diagnosis from blood panel, took home, fed water with syringe, I woke up every hour that night to check on her. At 2 am or so she was obviously too far gone to rush to emergency vet, and she died in my arms less than 20 minutes later. My vet had me take her home because he wanted her watched overnight, and told me to take her to an emergency vet if she got worse. Afterwards, I realized that, because I had to wait to get a cab when leaving the vet's office, she probably had already gotten worse by the time I set my baseline on her. I still think IV fluids and oxygen would have saved her, but there is no way to know.)

Maggie - aged 16 or so (adult stray when adopted), euthanized due to a chronic illness caught too late (forget what exactly; she was living with my mother at the time).

Zoey - 8 months - FIP (or some other unknown infection)

I was a kid when we had our first cat.. an indoor/outdoor named Lucky. I'm not sure how old he was, but he was poisoned, either intentionally or not.. the former wouldn't be a stretch, we have a neighbor who is known to have killed cats. We rushed him to the vet when we found him, but they couldn't save him.

And my dear Chase, who was 14, died of lymphoma.

toby died at around 9 years of age from a heart condition, i don't remember what, i was 14 at the time. he started with these attacks of trouble breathing that i can still hear. then he started swelling around the middle. my mom said it was fluid around his heart that was causing the swelling and trouble breathing. it was my job to give him two pills which i think only stressed him more. we were warned that he might end up paralyzed and sure enough in the middle of the night he woke me up crying and i found him on the floor, his hind legs paralyzed. we watched him die that night, it was horrible.
susie died of unknown causes at 18 years old. she had lost a ton of weight and stopped eating. when she became incontinent i had her pts to end her suffering.
jenny died of unknown causes at the age of i think 12. i think she actually passed just minutes before they injected her to pts, but did it anyway to be sure.

Comet (1 1/2) Died from kidney failure. He was the runt of a feral litter we adopted. He was always very very small. He had under developed kidneys which cause him to pass very early. Poor guy. He lives on through his two brothers and tehy miss him terribly

Peaches (13) Got ran over by a car. This was my very first cat. My parents let my brother and I adopt two brother cats. He lived with my parents when I moved away, and ended up getting ran over in our driveway by my Mom. As horrible as this sounds...this is the reason my cats live inside. I just do not trust that they will be safe outside.

Spookie (3) Disappeared one day. This was peaches' brother. He ran away...Yet another reason I keep my pets inside. Spookie was not microchipped because my parents were not into spending a lot of money on the family pets. I am complete opposite however. I love my babies and will do anything to have a long healthy life.

Our first cat, a siamese named Sassy, had to be put to sleep when she was 11 because she had cancer.

I have only lost one cat so far.

Sphinx (18 years old or so) was pts because of liver lymphoma, not from some other health problems he had - which included a level/grade 3 heart murmur.

I've only lost two.
First, the Siamese, she was fine one day, and her systems were slowly shutting down the next. She was 19 when we had her PTS, vet called it age onset systemic failure (AKA natural causes).

B.C. my last RB kitty, was PTS two months shy of his 13th birthday, he had widespread lymphosarcoma, likely due to over-vaccination (his last vet's words, not mine).
He stopped fighting 6 months after diagnosis.

Precious - died during labor - 5 yrs?

Duchess - CRF 15 yrs

Since mine arrive health-compromised, I suspect I've lost to many to list them all. The most recent

Cleo- 18 years old- outside kitty all his life-died from problems resulting from pet food contamination

Prowler- 4 years old- died of unknown causes- vet suspect contamination issue caused death

Stryker- CRF age 10

Noddy- hit by a car when he escaped from house

Tazzy died from brain damage after collison with car

After losing Tazzy we decided to build our cat enclosure so our ferals can be outside or inside and stay safe.

There is a new article about how household chemicals are being studied now to see if they might be the cause for the rising death and illness toll among cats. If I can find the link- I will post it later.

Klarisse - We think her liver. Passed away last night.

We had Fred sent to the Bridge when he began suffering from FIV he had lived with for years. He was my first cat, I had him for 18 years, and it was like losing a child.
We lost Leo and George to Feline Leukemia.
Webb and Georgia sneaked out and got hit by cars on 2 different occasions.
My most recent rescue was very old, declawed, toothless and ill when I got saved him from being tormented and abused by some teenagers. He jumped in the car with me, so I took him home, where he lived in my laundry room and back yard until he was suffering badly and we had him pts. The vet said he could not do anything for him, and it was the most merciful thing he could do. He estimated his age at about 20. He had been a pet, then was abandoned. There are a lot of elderly people around there, and I suspect he may have been turned out after his owner may have passed or been put somewhere to be taken are of. I was glad to be able to give him food, shelter and love during his last days.

Sunflower - bacterial pneumonia...he died before we knew he was sick.
Ditto - the same and worms. He was being treated but the medicine wasn't enough to kick it before he passed too.

RIP darlings!

Sommer almost 3 years old, died yesterday from feline hepatic lipidosis -- fatty liver. Vet doesn't know how she caught it since she was young and thin (usually cats are obese and older) and why it progressed so quickly. Healthy one day and 4 days later being buried in my backyard. Without an autopsy we will never know for sure, but the Dr thinks that it probably started with her pancreas so she would have died shortly anyway. At least with it being so quick she didn't suffer but it has really hit my husband and I really hard -- we keep thinking that we should have noticed something but the Dr even said there was nothing more we could have done. By the time she started to show signs of being sick it was too late. When does it stop hurting? We all miss her including the 2 other cats we have. We also feel so stupid for being so upset about it but until we had our human daughter 5 months ago, Sommer was our little girl and her brothers our sons.
