There was always a dog - most likely a beagle - when I grew up. In college, my roommate and I adopted a mutt, who inevitably became Mother's responsibility!
When I married, my bride and I realized that we just weren't going to walk a dog from our 3rd floor apartment! So, cats came into our lives.
That was in late 1958. There's very little time since then that there hasn't been a feline in residence!
The current Cat suits me to no end! She takes care of herself, even though I do have to clean up her litter pans; she sleeps with me, but doesn't really fuss if I inadvertently kick her off the bed!
To me, a Cat is the best companion!
