I have two older bunnies, 8 and 9, one has megacolon so I ordered these treats. The first day, both rabbits ate them up. I had to take away their other treats prior so they could get used to this new one. The bunny without the megacolon issue absolutely loves these so much! The bunny with megacolon is still figuring out if she likes them. She will eat half and leave it. Sometimes she eats the other half sometimes her bunny friend does! Today I’ve noticed her poops do look more healthy. They used to be large, dark brown and different sizes. Now they don’t look AS large or misshapen. I’ve also incorporated an arthritis treat for both bunnies which they both enjoy. They each get one megacolon treat in the morning and half an arthritis treat at night. So far so good! I’ll order these again when my first bag runs out to keep checking her progress.
