Help!!! How to trap kittens?
Talk to your local council about trapping them. Most councils will at least know where you can hire a trap from. You can always make a complaint to the dog catcher, and get them to trap the cats for you- talk to the animal shelter that they are taken to, and explain to both them and the ranger that you are interested in adopting the kittens. They will hopefully be able to adopt them out to you, and help you pay for their vet work. Usually the price of adopting the animal costs less than the price of the vet work, so this could work out the best, cheapest, and most humaine option.
