BTR: Have just insured a dog with Ellenco, have had to make a claim yet and hopefully won't ever have to. We have two cats as well but they aren't insured as being indoor cats mostly they are less likely to be injured IMHO.
The top reason for cat insurance claims is that they often get involved in fights.
Did you get a 10% discount with Ellenco? I googled and found this page but have no idea what the promo code is:
