necuno,
if you already have a kitten in mind and he/she is not likely to find a loving owner, go for it, but if you're still looking around, please consider the following before deciding where/whether to obtain a kitten:
adopting a kitten/cat from an animal rescue organization such as wet nose, paws, aacl, spca (or tears if you happen to be in cape town) will cost anything between R300 and R450, but don't freak out as this usually includes the following:
1) first
flea treatment
2) first
de-worming
3)
first vaccination (usually given at the age of 8 weeks, then a month later at 12 weeks, and again at 16 weeks).
NB. these 3 vacs, and the timing thereof, are vitally important.
kittens and puppies (as with human babies) have no immunity and unless they are vacinnated, could become very sick (and suffer a great deal of pain) if they come into contact with a diseased animal and/or its faeces/body fluids, so please have it done, not only to protect your kitten, but also to prevent him/her possibly infecting other cats. your vet will recommend a yearly vac thereafter and i strongly suggest you have it done, even if only for the first 4-5 years.
4)
sterilization (at the age of 6 months). believe it or not, but un-spayed female cats (and dogs) can and do fall pregnant from as young as 4-5 months old, so please ensure your kitten is never left alone outside until he/she has been sterilized.
5)
micro-chipping (not included by all rescue organizations, but a definite life-saver when an animal goes missing, so please have it done at your vet, if not done by the org you adopt from).
approximate costs of having to pay a vet for the above could be as follows:
1) R40.00 every 4-6 weeks
2) R15.00 every 3 months
3) R150.00 per vac
4) R1200.00 to have a female cat/dog spayed; R900.00 to have a male cat/dog neutered
5) R180.00
i would also feed royal canine or hills for, at least, the first year or two, but you can vary it with boiled chicken/fish/lean meat mixed with rice and veg (no salt).
never give a kitten/cat any milk - fresh water only - especially if your cat is going to be an indoors-only pet (which is best) and it uses a litter tray. milk = runny tummy = huge pong!
take photos (note all the markings) as soon as you get the kitten/cat (in case it gets lost, in which case, advise the organization you adopted from and also post ads on the net, send email to all vets in the vicinity, the spca, aacl, gumtree, pawtal, abandoned.co.za, etc).
love your kitty and always take it to a vet at the first sign of illness
ps.
if you have ever thought of emigrating, please think long and hard before adopting a pet or be prepared to pay the costs of taking your pet with you. nothing is worse than than seeing how easily people, who supposedly "adore" their pets, dump them at animal shelters or hand them over to friends/family, who will not look after them the way they did.
pps.
never remove a kitten/puppy from its mother before the age of 8 weeks, unless absolutely necessary. the main reason for not doing so is because you will be depriving it of the mother's milk, which contains antibodiies that are required until such time as the kitten/pup can be vacinnated (and not merely to avoid cats "kneeding" blankets, wool or your legs/boep later in life).
