Can my cat safely take human birth control instead of spaying?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed

My 1.5yr old queen is very aggressive and strictly against any kind of wound dressing. Since spaying is not an option, a vet prescribed human contraceptive tablets to be given to her (Levonorgestrel 0.15mg, Ethinyloestradiol 0.03mg). He said that 1 whole tablet must be given to her daily. Is this safe for my cat and is the dose prescribed by the vet appropriate?

IF you do not intend breeding then surgical neutering or possibly long term hormonal implants replaced every 6-12months would be preferable, It is possible to close spay wounds without any additional dressing, usingeither disolvable, internal stitches or suture glue and this would be a permanent solution, reducing the risk of side effects compared to treating life long with human medications which have not been tested in cats (or any patients of that size!).
