Joker had a follow up visit with the vet today. He had x-rays taken to see if there were any abnormalities in his digestive tract. Thankfully, all structures appear normal... he was just severely constipated. Poor kitty has been having chronic issues with constipation and vomiting. So he got an enema and I can't imagine he's still constipated after the massive load he unleashed. He's getting Miralax daily and I'll make some dietary changes for them too. I'm researching higher fiber foods, which the vet recommended. She gave me a link for prescription food, but it's prohibitively expensive. Although I'll get it if there are no viable, cheaper alternatives.
