Smaller biscuits are easier for older cats
My two old cats love these biscuits. One is 18, the other 12 and they obviously find them easier to eat than the bigger biscuits of most other brands. They are rarely (if ever) sick after eating them - which may be because they find the smaller size easier to chew and digest or maybe it's because of the ingredients. Either way, these biscuits seem to agree with both cats.
