The US Department of Agriculture (USDA) says it will stop killing cats in a research programme, following strong public criticism.
The animals were fed with tainted meat, and the parasite’s eggs gathered for use in different tests.
After the examination the animals were euthanised.
Veterinary groups state that the disease is treatable and the felines ought to have been adopted.
In excess of 3,000 little cats have been put down since the program was propelled in 1982, campaigners the White Coat Waste Project (WCWP) state, with the program costing more than $22m (£17m).
In an announcement, the USDA said that “toxoplasmosis research has been redirected and the use of cats… has been discontinued and will not be reinstated”.
I commend the USDA for their decision to end this type of testing on kittens. They listened to the people and responded appropriately to our concerns. This is how our institutions, our government, and our democracy should and must work. https://t.co/l9TJ7ifTRW

One of the key figures behind the bill, Democrat Representative Jimmy Panetta, said the declaration demonstrated what was conceivable in governmental issues.
The 14 remaining felines on the program are to be embraced by USDA workers.
The office has said its exploration split the rate of toxoplasmosis contaminations, which is especially hazardous for unborn youngsters and individuals with compromised immune systems.
