The first I heard about this kitten was from a stall-holder at the nearby kopitiam who mentioned "a very funny-looking kitten scampering under the tables and feet of her customers" seemingly unconcerned about any danger of being trampled underfoot. It was contentedly chasing bugs and playing among the litter. I brought it home to observe for a couple of days, hoping for the mother cat to appear (no such luck).
Perseveringly charming and 'humble' to the others, he has managed to win the trust of my other 3 cats in 2 weeks. It is Teddy's modus operandi to go up to a stretched-out cat on the floor and snuggle up to pseudo-nurse. Even though all my other cats have been neutered, I think instinct kicks-in upon this nursing action to calm the nerves of all concerned. So Teddy now has 3 pseudo-moms who will groom him and allow him to snuggle up to them! Monti, my oldest male cat, plays the part of big brother (sometimes mother!) and seems to be the most tolerant of Teddy, allowing him a wide measure of freedom for mischief.
Unfortunately, I can't keep Teddy permanently due to space constraints and I worry that 4 full-grown cats under one roof may be a little too much to ask of my feline friends.
All signs indicate that Teddy is very accommodating and may be quite partial to sharing living space with other cats (subject to the normal feline introduction procedures, of course)
