Hyperthyroid cat on Hills Y/D diet, extremely thin?

Thanks for reaching out. I completely understand why you're worried about your cat's weight. Managing hyperthyroidism in cats can be challenging and seeing your furry friend still struggling can be concerning.



Hyperthyroidism often leads to weight loss because it speeds up metabolism, even if your cat is eating well. The Hill's Y/D diet is specially formulated to limit iodine intake, which can help manage thyroid levels. However, if your cat remains extremely thin, it's essential to consider a few possibilities.



First, ensure your cat is eating the recommended daily amount of the diet. If they’re eating enough but not gaining weight, it’s possible the hyperthyroidism isn’t fully controlled. There might also be other issues at play, such as gastrointestinal problems or kidney disease, which are common in older cats.



At home, monitor your cat's eating habits, energy levels, and check the litter box for any changes. You can also provide small, frequent meals to help with calorie intake. Always ensure fresh water is available, as hydration is crucial for their overall health.



Watch for signs like increased thirst or urination, vomiting, or diarrhea, which may require immediate attention.



Consider booking a video consult with Dial A Vet. Together, we can review your cat's overall health, diet effectiveness, and possibly discuss further testing or treatment adjustments. This will help create a comprehensive plan to get your kitty back to a healthy weight.
