Are there any obvious signs that a cat could be lonely or depressed? My one year old cat doesn't seem to want to play much anymore. She just wants to sleep and eat. Sometimes she'll be in the mood to play 'hide and seek' but that's not often. She has every cat toy known to man and a cat tree and a cardboard playhouse. Also my DP works part time so she's got company. Why does she seem like a little saddo
