What is the best way to deworm feral cats? Hi, I'm Doctor Greer, Director of Veterinary Services with Revival Animal Health. To deworm feral cats you'll need dewormer and milk replacer such as Breeder's Edge Foster Care Feline. If a cat has never had milk replacer given to them in the past, it can take about three days for them to warm up to the idea. To help establish trust, start the process with unmedicated milk replacer. As you feed the milk replacer in several pans at the same time for three days, get a count of how many cats are in the colony. Next, establish how much dewormer to add to the milk. The average feral cat weighs eight pounds, so multiply the number of cats by eight to get total weight. For example, if there are 20 cats, then the needed dose of dewormer is for 160 pounds. We add that total dose to the milk replacer. If you have a large colony, be sure to use multiple pans to make sure all the cats get a chance to drink. On your first time deworming, repeat in seven to 10 days to completely remove the external parasites, eggs and all.
