Q. My cat urinates frequently and cant sometimes? Sometimes red liquid? Is it UTI? How can I treat it? How much for help from vet?
A. You need to be very careful with urinary problems in cats. Keep a close eye on your cat when urinating, is he/she passing a reasonable amount of urine.? If not sure, or if passing only small amounts, you need to take him/her to the vet urgently. Not being able to pass urine is classed as an emergency and can lead to rapid deterioration and eventually passing away. It might be that it is just some bladder inflammation/cystitis, but I can't say for sure without seeing your cat and having a full medical history, more details about your cat etc.
