Thank's for your advice which is really valuable and wonderful you have given the correct answer let him implement it in a trial and error mode.
Now presently I am having 5 big and 3 small one's..
Sometime's one or two doesn't survive that's normal and natural we cannot do anything with one which is suckling and eye's not open.
Let me ask you a question is there a method of birth control by providing a tablet for the female cos the other media of taking that to a vet - mission little bit impossible and I have failed on that attempt with my stray orphanage cat's...
To be frank raring and caring a stray cat is easy but when it come's to pregnancy that's the worst part - sympathy and pathetic strike's into our heart and vein's how to discard them along with mother ? that's another problem so the generation stay's with us...
Unlike for a rich person a persian cat is adorable but it's quite expensive to manage.
No., there are no Tablet method for the cats

..
but, there is a vaccine which is available with the Vet's that prevent cats from breeding upto 1 year.
Although it's not advised to give it more than 2 years in a row., as it will cause Fallopian tube cancer in female cats !
Do know that unlike dogs who rely more on smell for their cues.. cat's depend on their Excellent hearing and vision.. so if you ever want to take a feral / stray cat to a vet do the following..
1. Grab the cat by the collar (neck - close to the skull.... not close the legs., as it will obstruct it's breathing tube)
2. Snuggle the cat close to your chest (a thick shirt would be good thing to wear)
3. Make sure to hide cover (cup) it's eyes & ears with your other free hand.
Sounds crazy., but you will be amazed on how calm the cat can be after10 -15 seconds.
So get someone to drive you to the vet and bring it back the same way.
Remember that if you put a cat in a gunny bag or some kind of restraining compartment, unlike the dogs... cats develop claustrophobia and stress far too quick and tend to be more violent and not be receptive to the medicine they are given.
hope it helps mate
