I have been brought presents of baby bunnies, lizards, snakes, birds and rodents, often alive, also a mink's tail once. Bugsie rarely makes a noise, so I groan when I hear him enter the flap announcing his arrival! It is the only time he meows.
The other day I smelt rotting flesh in my living room, seeming to come from behind the dresser. I emptied and moved it with great difficulty and found nothing, only to later find a dead mouse in full view under the table! It must have been there a few days to smell so awful! (I don't vacuum very often).
Honeypot, you can get worming treatment on spot-on form now, which is applied in the same way as flea drops, behind the neck. No need to try to get tablets down the cat!
