What does this mean. Is she dying

Thank you for your question. It would be best to have your pet seen by a veterinarian, as they will be able to examine them, see what might be going on, and get treatment for them.

On certain areas of my cat the skin is blue. I don’t know what’s going on.

Thank you for your question. That may be a ringworm lesion, or a trauma. Skin darkens when it is chronically irritated, and it would probably be a good idea to have your cat seen by a veterinarian to see what might be going on with the skin and what medications may help. I hope that all goes well for your cat!

Sprayed my kitten 13 weeks old with natural care plus flea and tick spray, and her skin not fur turned blue

Hello, thank you for your question. I am sorry to hear that your cat's skin has turned blue! Without examining your cat, it is very hard for me to know for sure what might be going on. What you describe could be consistent with staining due to the product itself. I recommend using some water to gently wash off the flea product. I would call your veterinarian tomorrow to ask for other suggestions for flea and tick care, as this product is not very effective at preventing fleas and ticks long-term. I hope that your cat's skin clears up soon!

The cat threw up yellow bile here and there i thought it was usual hairball of the month. However i left the cat alone for a few days for a small trip and when i got back still hadnt finished its food like normal usually i fill up like a half gallon with his food and another 2 half gallons with water whenever i leave him for more than a day and this time i got back and the food was all there including the water and he is very weak. His symptoms are blue gums it feels like his kidneys may have swelled again (he had a uti last year) he likes to be in the garage. I think he might have ate a rat that might have been poisoned by neighbor or possibly licked some antifreeze. Either way he has blueish gums, a swollen organ near the hind legs causes him pain to touch,weakness, depression, had like a seizure of sorts getting out of litter box, extremely shaky,and elevated breathing.

Take Zeus to a Veterinarian (regular or emergency) immediately, there is nothing I can recommend you do at home at this point since it seems that he may have been this way for a few days if no water or food was touched. Regards Dr Callum Turner DVM
