It's possessive he/it = sein. Katzen is plural so it's Sein(e) Katzen. I hope this is correct. Learning for 4 weeks. Hopefully somebody who knows german better will confirm :)
Ah I see.... it is plural for his... instead of his cat 'sein' it would be 'his cats' Seine, plus Katze is feminine.....
Just want to thank you for the new female voice. I had trouble with the previous one, which seemed to gain some buzz and make it hard to understand sometimes. I find I don't have to listen over and over again to hear this one.
If Seine can be both female and plural, how are we supposed to know (in this case) that the owner is male? It seems like there is a 50/50 chance of getting the answer right.
