Lungworms in cats
Aelurostrongylus abstrusus infection is relatively common in domestic cats and is the most important lungworm in cats (other lungworms are Troglostrongylus brevoir and Capillaria aerophila). Referring to Aelurostrongylus abstrusus as a lungworm is quite misleading. Although the early stages of the parasite do affect the lungs and severely infected cats may cough, other signs are far more common. The parasite itself may not cause the cat any problems unless present in very large numbers. All cats in the UK are potentially at risk but outdoor cats and particularly those with a compromised immune system are more at risk.
