OK, now here is another update.

JIM......he blockede once, from crystals.'
'
He has been eating the Innova Evo (dry) for the same amount of time as Biddy, but his urine is MUCH worse! Totally loaded with crystals.

He is now suppose to eat 90-100% canned food.

I suppose we'll go with the prescription foodl or possibly the EVO canned.
