A woman up the road has two little black kittens. They're adorable, but don't seem to be very well looked after. This morning, one of them followed my two into the house, barged my big adult male cat out of the way and ate his breakfast. I know cats are very good at trying it on, but this one looked genuinely hungry.
SIL, who lives near us, has been trying to tempt them in, and I posted in AIBU recently and had pretty much unanimous agreement that she shouldn't be doing this, they belong to someone.
SIL and BIL now have fleas in their house. They don't have pets of their own and are very houseproud, so there's a limit to where the fleas might have come from.
The kittens always appear hungry, but are really friendly so I don't think they're being actively ill-treated. We're worried that they're not being fed and they're clearly not being de-fleaed. They're approximately neutering-age but haven't been done.
What, if anything, can I/should I do? I don't want to steal them, I've got my own cats. I just don't like the thought of kittens being neglected and unfed. Any suggestions?
