in january 2010 i had my female cat spayed at a ospca spay and neuter clinic. About a year later she started exhibiting signs of going into heat, it has been getting progressivly worse each time she goes into heat and like probably 10 to 12 days between her heats. They have gotten this close together since about november of 2011, she also pees everywhere. Ive had her checked for urinary tract and had her treated for it, and i really need help. Ive also tried to give her a calming drug amiltriptaline and had feliway air plug ins and given her cat nip twice a week. Honestly i dont know what else to try, they would redo her spay for free but the vet i go to here says chances are they wont find the tiny bit left over from the spay. Please i need advice.
