Following a blood test, our cat, Spot, has just been diagnosed with hyperthyroidism. She's 13 (nearly) and was losing weight whilst eating non-stop, vomiting regularly after eating and generally acting very hyper! For the past week, since she's been taking 5mg a day (2.5mg every 12 hours) of Felimazole, she seems to be back to normal. We chose this drug because she would be able to eat normal food instead of something different to our other cat, Tommy.
My question is the best food to feed her now. Since her liver enzymes were very elevated too, the vet said she needed a special liver food so advised us to feed her Royal Canin Hepatic dry food. I hate the idea of her eating just dry food and so I asked why we could not feed her the raw ground rabbit (no thyroid now of course!) and chicken meat/bones that we supplement with taurine, vit E, salmon oil, vit B and he said she shouldn't eat bones no matter how fine we were grinding them and that she needed a special diet for her liver. I bought a small bag at a big, big price...
I've read that hyperthyroidism can affect liver enzymes so now she's getting treatment for the thyroid, maybe the liver will improve too.
Reading the pack ingredients for the Royal Canin food and finding the first ingredient to be rice, surely that can't be good for her? We've always tried to feed our cats on animal protein alone and generally they've thrived on it. Now I'm faced with this quandry about what to do for the best for her.
Any advice would be welcome regarding food for her in the short and long term and also the drug treatment - anything better out there?
