WHERE:

Br. ljusaka:
25 (rijetko 23, 26 ili 27) leđnih, 187-234 trbušnih i 56-90 para podrepnih.
Scale count:
25 (rarely 23, 26 or 27) back scales, 187-234 belly scales and 56-90 pairs of subcaudals.
Stanište:
Često ih se može naći na rubovima šuma i živica, u otvorenim šumama, na obraslim kamenitim padinama. Preferiraju nešto hladovine i vole topla, relativno vlažna staništa i može ih se susresti u močvarama i kraj potoka i bazena.
Habitat:
Often found near wood edges and hedges, in open woods, on rocky overgrown hillsides. Prefers some shade and likes warm, rather humid environments and may be encountered in marshy areas and near pools and streams.
Ponašanje:
Dobro se penje i pliva. Kravosas je realtivno flegmatičan i sporije se kreće. Naša najpitomija zmija, gotovo nikad ne grize. U početku može dojmljivo puhati, ali od toga ubrzo odustane.
Behaviour:
Climbs well and swims. The Four-lined Snake is rather phlegmatic and slow-moving. Our most docile snake, almost never bites. Can hiss at first, but quickly stops.
Prehrana:
Često lovi plijen za topla, oblačna vremena i u sumrak. Veći plijen davi. Hrana odraslih se pretežito sastoji od manjih sisavaca (do veličine štakora i mladih zečeva),  ptica (pogotovo ptića koje lovi pretežito u proljeće), jaja i povremeno pokojeg guštera. Nekad zalazi u kokošinjce. Mlađi se pretežito prehranjuju gušterima.
Food:
Often hunts prey during warm and cloudy conditions and at dusk. Large prey is constricted. Food of adults consists mainly of small mammals (up to size of rats and young rabbits), but birds (especially nestlings) are taken particularly in the spring. Eggs and occasional lizards may also be eaten. Sometimes raids poultry yards. The young take a relatively high proportion of lizards.
Razmnožavanje:
Ženke se pare skoro svake godine, barem na nekim područjima. Lijegu 4-16 jaja (30-70 mm u dužini). Mladi se izlegnu za 7-9 tjedana i dugi su 20-40 cm. Spolno su zreli s 3-4 godine.
Reproduction:
Females mate almost every year, at least in some areas, and lay 4-16 eggs (30-70 mm long). Young hatch in about 7-9 weeks and are 20-40 cm long. They mature in 3-4 years.
