I have had a year old sugie and a 2 year old sugie, i have had both for a year, they new fought until a little while after having them both for a year. Gabby, the 2 year old, crabbs at Lola, the 1 year old, scaring her into giving gabby her food. i tried to read up on it but my sources are scarce, hardly any of the websites had nothing on 'fighting'. so now for 6 days a week i separate them into different cages, on the 7th night i put them together and see how long it last be fore they fight. the longest it has lasted was 2 weeks, should i be concerned?
