I adopted the kitten that hung out around my door.
What made you adopt the kitten?
The kitten will be a good company for me, I already have a dog.
Giving an animal a home is really nice. You should make sure you take the kitten to the vet as soon as possible. If not, they might develop health problems.
I don't think that's true.
It's kind of you to give the kitten a good home. Giving the kitten a good home also ensures making sure that they are doing well health wise.
