Hi.. Im Jen..my sister in law owns the mother of my cat chu.. I had enough finances to fix mine but her mother is still unspayed.. On july 10th.. She went into heat and nated for 3 days and now hasnt beenin heat since then.. She honestly went in heat 2 times every month before this so its odd. Shs about 6 or 7. Do you think she is most likely pregnant. Shes a very small cat too so not sure how to know for sure if shes pregnant.. Cant afford vet confirmation so need advice on how to know for sure.
