Can I submit multiple data feed to Google Merchant Center?

[CommercePundit]

I have submitted my product feed to Google Merchant Center. There are 7K+ products in one product feed. (data_feed.txt)

I am not satisfy with my products' performance on Google shopping. Because, I am not able to maintain data quality for all products as well as not able to focus on high selling categories.

Can I submit multiple product feed with separation of categories as follow.

category001_data_feed.txt (With 200 High selling products)

category002_data_feed.txt (With 100 offers products)

I read some where as follow. So, which is right? I am too confuse...

a single feed can handle up to about 100,000 items of
all types and categories -- from handbags to hammers.

up to 10 feeds may be registered for up to 1,000,000 items.

multiple feeds are mainly intended to submit
more than 100,000 items -- not as a general
separation of products.

there are various issues associated with multiple feeds
that should be taken into account -- such as coordinating
unique id values across all feeds and update and upload
coordination issues; but 10 registered feeds are allowed.

Yes, you can have multiple feeds but cannot duplicate product or submit feeds for the same product for multiple domains that you own (ref)
