Abandoned Cats - very small kittens

I've been reading a post at Emma's blog http://word-stuffing.blogspot.com/ [and she's kindly posted the reply I made] and obviously the thing to do with abandoned cats is to take them to a shelter if you can, unless you plan to adopt! however if you find yourself lumbered with very small kittens it is imperative to realise that they cannot pee or crap without a bit of help.
After feeding with a dropper, dolly's bottle, syringe or dedicated feeding bottle [there are a variety of formula mils for kitties at pet stores and the vet, and at a pinch I have used SMA] it is imperative to stimulate micturition and defecation by holding kitty on her back in one hand and using a piece of damp towel to simulate mum's rough tongue rubbing down the belly towards the tail.  Kitty should obediently produce. Mummy cat eats this or washes it away - just wash it off with your damp towel and use a clean piece for the next kitty.
Remember new kitties must be fed and toileted every 2 hours round the clock.  It is GRUELLING - but rewarding! after a week or so you can drop to every 4 hours.

2 week kitties

At 3 weeks you can begin to introduce solid food though the kittens shouldn't be fully weaned before about 6 weeks [one reason poor Worrals has sucking issues having been abandoned by mummy at 4 weeks].  When given a feed, solid or bottle, you can then try introducing kitty to a litter tray.  For little delicate toes, sawdust might prove a better incentive than granular litter.   If nothing is forthcoming, continue to use the method of stimulating with a damp towel.  They should however soon get the idea.

4 week old kitties

Our kitties were happily producing at 4 weeks old in the litter, which made life easier and were perforce more weaned than ideal.  I continued feeding with formula milk for the next 3 weeks as well however.
