Info: Chelsea, female. Six years old. Has lived with several other cats prior to now, as well as a dog.

For as long as I've had Chelsea (four years) we've always lived with other cats or other people (usually both). About a year ago I moved into an apartment alone and it was just her and I. Around this time I noticed that whenever I came home from work she usually cried at me and when I picked her up she would put her paws around my neck and dig in a bit to attach herself to me, similar to a slightly painful welcome home hug and would rub her face on me. She would basically follow me around and meow at me for at least 15 minutes after I get home. She never did this prior to us living alone so it worried me. I also found out that she tends to whine when I leave. My current apartment does not allow me to have two cats but I will be moving in March and this place will allow me to. 

I guess my first question is, is she in distress? Is she having difficulty being alone all day and sometimes all night at times when I have to stay at work? And if she is, would pairing her up with another cat be helpful for her? And if so, what are your suggestions?

Thank you!
