Ok the cobwebs would be comic if it weren't tragic, but this is still somewhat relateable with Emma, who had more and more trouble passing things as she got older. I don't know if this qualifies as advice, but, for what it's worth, we eventually moved to just wet food and at a vet's advice, started mixing in about 1/5th canned pumpkin puree. Doubt that will fix anything if cobwebs were the problem. Emma always really really loved gnoshing on plants. It made her puke but we tolerated that thinking she must be doing it for some reason. I think the puking was less bad if she had a steady supply rather than binging. So, lots of wheat grass. Wondering if Hope might displace some of the cobwebs with greens? Sorry, just coming in to this discussion, so apologies if this is well covered territory.
