no, it doesn't sound like cat. Have you got a photo?
they'll just be potatoes.
I think it's buttercup
see your other (duplicate) post
the first is a Cirsium, maybe Cirsium rivulare
the second Lysimachia atropurpure
3 is Nectaroscordum silicium
I don't know 'White Swan' but it's euphorbia and I think it is flowering.
