What Is Lungwormin Cats?
Cats can get several different lungworms in North America . The most common eccentric in domestic cats isAelurostrongylus abstrusus , but cat can also get several other coinage of lungworm .
cat with lungworm have adult louse living inside their lungs , and unripe larvae go around the lung . The irritation make cough , and the insect can take up so much space that computed tomography have job suspire . It can be straiten for cats , and the symptoms can become wicked enough to become fateful — especially in new kittens , who can get the contagion from their female parent ’s milk .
How Do Cats Get Lungworm?
cat commonly bewitch the lungworm by eating septic rodents or bird ( for most species — although one sponger metal money can also be picked up from cat poop ) . Once they ’ve been eaten , the parasite enters the bloodstream and travels to the lungs , where they get on into adults . These adult parasites produce eggs , which hatch , and the first - level larva are coughed up and unsay .
These petite larva survive the stomach and intestine and are then passed in the poop , ready to taint a punch or escargot . Inside the slug or snail they grow , and are then able to infect cats again — although usually , they first infect a shiner or bird that eats the slug or escargot .
This means outdoor cats , and especially stray who hunt a lot , are much more likely to have guy lungworm than those who drop most of their time indoors .
Most lungworms need to drop some time in an intermediate host ( in this character , the snail / slugs ) to develop the right way .

Signsof Lungworm in Cats
The signs of lungworm in cats vary staggeringly . In some fount , cats can be infect with lungworms without showing any signs at all . This is called an asymptomatic transmission .

A smear of poop is examined under the microscope to look for the first - stage larva , which are very participating and easy to see ( although unmanageable to distinguish from some other larva ) . Eggs are n’t produced systematically , so collecting poop over several days or trying again several metre might help .
There are several other tests that might help identify lungworm in true cat . The best is credibly a PCR trial , which check the poop ( or a throat swab ) for the presence of lungworm DNA .
