Thought I'd do an update - Monday I went to P@H at lunchtime, ostensibly to look for samples of Barking Heads and Wainwrights. Ended up speaking to the in house "nutritionist",who had never heard of Eden or Simpsons, but who from a behavioural point of view thought I should stick it out for another week or ten days (after one week already) being as strict as possible. I don't really put much faith in their "qualifications" but she seemed nice enough, and actually advised me not to spend money lol.
However, I HAD already ordered a trial size of Simpsons 80/20, so thought at least that was there if I caved in.
Since then - dinner last night she ate about two thirds, with me holding the bowl. Today she ate no breakfast (thoigh was trying desperately to see what I was eating) and then this evening ate two thirds straight off, and the rest I did as "find it's" around the house which encouraged her to eat it.
Additionally, the trial bags of Simpsons 80/20 arrived and she seems to love it. Used it as training treats, and she was actually harrumphing if I wasn't giving it to her quickly enough, which was encouraging. I did the "Whiskas test" as well - Simpsons in one Hand, Eden in the other. Derogatory sniff at Eden, went loopy over Simpsons. I was thinking I would persevere for moment with Eden as have so much of it, but the more I think about it, I can't help thinking she was never as enthusiastic about Eden as she is about this new one, and wouldn't it be better to give her something she actually wants? And I am encouraged now that my willpower can be greater than hers, and she will eat....eventually.
At least I know there's someone who'll take the Eden of my hands if I switch over now....
