Kassitatra (Kassitatar)

Possibly dialectal version of harilik kassitapp, the field or common bindweed, aka withy wind, small-flowered morning glory, creeping Jenny, possession vine, etc., Convolvulus arvenvis, sole variety of Estonia. At first/last: Kivi seems to have made a mistake: street not in Tallinn but nearby Muuga, then again, perhaps Muuga was part of Tallinn in the eventies?...
