I also have a house full of animals, since I keep a variety of rats, mice, hamsters, reptiles etc. I see death too often, mostly since the rodents don't live very long
I wish they could live to be 20 years or so, but then I probably couldn't have had so many rescues :P Just a list of what I have lost in my pet keeping. I know it seems a lot, but keep in mind most of these animals were old rescues, and the other rescues were sick when I got them and despite vet care, couldn't be saved
Ozzy, Eve, and Cheech- trio of banded geckos that despite numerous vet visits and high bills, were too sick when I got them
Oliver- crested gecko rescued (had a broken jaw)
Kermit- red legged pan frog (old age) lived to be 6
Frankie- green tree frog (old age) lived to be 6-7
Muad'Dib and Mobuddha- two horned frogs that died of metabolic bone disease because Petco never gave them calcium powder. I had them both for a short time before they had to be put to sleep
Tristan- rat rescue old age
Pookah- Tristan's brother , old age
Skeeter- rat born here from a rescued pregnant rat (internal abcess)
Casper- rat born here as well from same rat (old age)
Howie and Gus- mice that died within 2 weeks of being here. One from an abcess in his mouth that made him need to be put to sleep. Gus had heart problems and died in his sleep. Their brother Brownie is alive and doing great a year later.
metallica- baby newt (ill)
Herbie- Hermit crab that died from stress two weeks after coming here. He hardly came out of his shell, even when I got him. His two buddies are doing well here.
Homer- my hamster Nemo's Dad. he was rescued from a family that couldn't take care of him, like his son. He died of old age at 2 years old.
