Pretty certain my lovely pair have got fleas ☹️
I've got one who is very friendly and sociable, so spot-on treatments won't be an issue with him and I've got some ready for when he shows himself later - but I've got another who chooses to be in an indoor cat, is very nervous and won't let anyone touch her. She's a rescue from Celia Hammond.
We've progressed to the point where she will sit within a metre or so of people, but gets jumpy if they move and will run to hide.
Its been a long time since I've owned cats - what treatment might work for her, as spot-on will be a non-starter but is the go to for all other cats I've had/known.
Also, how do you treat your house - there seem to be a lot of different approaches online!
