We have one cat (adopted stray) that ranges free out of doors - had a bad
case of worms, so treated with worm pills.

A few days later, one of our other cats, indoors only, has started a bout of
diarrhea.

Are these things related?

Thanks,

Probably.

Take the sick cat to the vet before he/she becomes severely dehydrated
and/or gets enough of an electrolyte imbalance to be in very serious
danger of kidney failure, heart failure, or something equally serious.

Diarrhea must be treated promptly, in cats. They can die from it.
