Thrive 100% Tuna Cat Treat MaxiTube

I have been buying Thruve tuna treats for a long time and always order 2 of the large tubs at £19.99 ( not cheap for treats!) however my cat really likes them so I make sure I always have enough. The last 3 orders, that's 6 tubs, I've ordered seem to contain lots of loose powder & less chunks. I wrote to Thrive suggesting that the chunks were smaller & more powdery & that this needed to be looked at, but never even got an acknowledgement, even though I have been a loyal long standing customer. This is very disappointing & very poor value for money now.

Normally I buy white fish as treats, but last time I tried the tuna one and my cats love them.
