@blueveinedthrobber,
Hi Bear, are you feeding them tinned food?
Ours are eating kangaroo fillet or lean beef scraps (straight from the butcher) topped up with dry feed(Royal Canin Maine Coon) . That seems to be a big improvement. Making them chew is good for their teeth according to our vet, and wet tinned food is no challenge at all, and dry doesn't get the sawing action going required to clean their teeth.
We have tins as a backup (for cyclones and forgetfulness/busyness) and every time we have to use it the smellometer goes off the scale....
