Five things were observed;
1 Lions suffer from extreme halitosis, they had little or none while following the vegetarian diet.
2 Their skin and coats were fuller and cleaner.
3 There was a notable change in temperament, they were less lazy ( more inclined to play) and very docile ( less aggressive.)
4 They ate slower, enjoying their food instead of rushing it.
5 Their overall physical appearance was better, they appeared to become sleeker.
It just goes to show that a vegetarian diet can assist more of Earths wonderful creatures other than man!
Food for thought!!!!
