And what is the most important change, you might ask? Well, it's official -- HEB has now stated that PIGGYBACKING is a go right there in the coupon policy! We have been able to piggyback coupons for some time, but it was really dependent on finding stores who were coupon-savvy and understood that piggybacking is not the same thing as stacking.

Species most active during both dawn and dusk (or twilight), are crepuscular. You could call crepuscular species both matutinal and vespertine. Some examples of crepuscular animals are skunks, fireflies, and deer. Pets generally considered crepuscular are dogs, cats, rabbits, and hamsters. As @Critters notes in the comments, sometimes hamsters are considered nocturnal.
All cats have elliptical pupils and round corneas with almond shaped eyes. The dilation of the pupil is controlled through two shutter-like ciliary muscles.
