I have a friend who had 2 cats so they have company when she's gone.
One got out, and was gone for several days. We went to a shelter and another friend and I persuaded her to get two cats, as they were so sweet and pretty.
About two weeks later, Tommy came back - he was sitting in front of her house - looked like he was waiting for her. Never told shere he was or what he did, but must have had a good time, as he was healthy, clean, and had not lost weight.
So now she had 4 cats, which is 2 more than she really wants. Then one of them developed a psychological problem (destructive when friend was gone) so she had to find a new home for her.
So, now she has 3 cats.
