I got two, but they put the policy no and not the cat name on, which was annoying. I have also recently had a claim through for Zi and they have changed that too - I got the letter confirming I would be paid 2 days after I had cashed the cheque (and I didn't do that the day it came in either!!). I know when I had a query on Buster I rang and it said Sainsbury's, when I queried they said they dealt with both, so maybe this change is to stop that.
Interestingly, Mollys renewal was identical to last year, despite them paying out £165, Zi's has gone up by £7 a month - money wise I have probably had slightly more out of them, but it has been done over 3 claims rather than Molly's one, but Molly's was before they changed the website (and excess), and Zi's was after.
