Hello, my name is Iqra. I had rescued a male cat in October last year. He was teething at that time. He had grown molars in November. Now he is still teething as his front teeth are coming.? My question is how old he is?

Normally all of their adult teeth have grown in by the age of 6 months. So if his adult canine (the large pointy ones) have grown in then he is likely done getting all of his teeth and over 6 moths old. Unfortunately, some kittens will continue to "teeth" or be mouthy until they are well over 1 year old just because that is kitten behavior. I hope this answers your question.
