Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
Do you think her thirst has increased? Or her urination?
Is Domino keep to eat but then struggles or gives up?
Or does she have no interest?
Any signs of drooling, pawing at her mouth or grinding her teeth?
Any changes to her breath (pus or ammonia scented)?
Any retching, hard swallowing, lip smacking, or vomiting?
her thirst has not increased, she does struggle to chew a bit then gives up,no sign of drooling, paw mouth or grinding teeth, there is no smell from the mouth, no retching,lip smacking or vomiting, but she does swallow a bit quick
Thank you Joan,As I am sure you can appreciate appetite decline in cats can be triggered by a range of conditions. Therefore, we have to consider her ongoing health issues along with other factors to help us narrow down the causes for her signs. Based on your additional history, I would be most suspicious that we are looking at an issue not related to her hyperthyroidism. Furthermore, her lack of other signs make differentials that could induce nausea (a very common reason that cats go off their food) less likely as well. And if she does struggle to chew before giving up (suggesting she wants to eat but that the struggle is too much), then I would be most concerned that the root of our issue is oral based discomfort. The reason is because unlike dogs, cats will avoid pain even if it means starving themselves. So, if a cat tries and cannot eat comfortably, then will often abort eating even at the risk of it causing havoc for their body.If we consider issues that would induce oral discomfort, there are a few. Now I am glad that she doesn't have an odor to her breath or increased thirst since kidney disease (a condition we do always have to be wary of at her age) can cause uremic oral/throat based ulcers that often are painful and put cats off their food. Other common causes we'd have to consider is whether she has dental disease (ie gingivitis,resorptive lesions, a rotten or fractured tooth, etc), or even an oral tumor (which can arise like ulcerative lesions under the tongue or in the back of the throat). With these differentials being the most likely for her signs, I would advise that these would be something to have her vet check since we don't want her to progress to a stage where she is completely off her food. Depending on their findings, it may just be a case of antibiotics and feline friendly pain relief to help her to settle but if she has a fractured tooth or one with an ulcerative lesion of the gum, then you may need to discuss its removal with her vet. Overall, Domino is giving you clear signs that she is in oral discomfort. Therefore, it would be prudent to have her vet examine her mouth. Depending on their findings, they will be able to advise you on the best course of action to address this for her. And in the meantime, until you can have her mouth examined, I would suggest trying her on soft pate style cat foods, meat baby food (without garlic or onion powder), or a veterinary critical care diet (ie Hill's A/D (LINK), Royal Canin Recovery (LINK), or Clinicare Canine/Feline Liquid Diet (LINK)) to just make eating easier for her and to make sure that Domino is getting proper nutrition into herself despite her sore mouth.
