My apologies for taking so long to respond. I've been having computer problems... Grrr! Thank you for your insight, though. I really appreciate it. Dexter started refusing to eat frozen/thawed awhile back, so it would be sorta difficult to add the Nutribac to his food. I did give him another small dose of Nutribac mixed with water orally a couple of months ago right after we relieved him of his impacted urates, though. I had the vet give him a 1 gram dose of it orally last winter when I had him there as well. How often would you recommend giving him 1 gram doses (as prescribed on the back of the Nutribac container) and for how long? That's a good idea about the baby food...
He hasn't been x-rayed...
