2021 - What I did today

JJB, can you ask their vet for some proper flea treatment - I don't think some of the off the shelf stuff is very good - if that's what they're using.
Sarris has a few cats - maybe she can recommend something?

Been there done that. We used to order Frontline for them until the home visiting vet said that theirs was a lot better. I understand they are using the vet recommended product.  I suggested they ring the vet, council or local pest controller re the 'infestation' and I believe they  contacted  the council today (Sunday) and left a message.  Meanwhile I caught another flea on me this evening!  The blighters have always loved my blood.  I'm traipsing around in white long socks so I can spot them before they bite. I feel like I'm back at school
