I adopted a 3 yr. old Calico and we have become fast friends over the past 10 months - she has learned to trust me, sleeps with me and shows plenty of playful, affectionate behavior. I am single and am gone weekdays, all day. I thought I would get a younger cat or kitten for her to play with during the days when I'm gone. Given my lack of time for kitty training, what would be the youngest age appropriate - and would this threaten Callie's feeling of security with me?
