I want to release the family "pet"
Why do you want to release the pet?
The cat gets way too much attention.
This is a family pet and you shouldn't release them. They could get hurt and it will hurt your family.
LOL, we have a gold fish, so no one will care about the cat.
It would be cruel to your cat to release it, as it wouldn't be able to survive well outside. I'm sure your family would miss it. You should commit to providing good care to a pet.
