Yeah, I'm just quoting the book. I don't know for sure by any means. That explanation makes sense to me since there are so many cats that are euthanized every day.
Now that I'm thinking about it, I had a woman in my A&PI class that had taken it before at another school, and she said that they had extra large cats that had been imported from Mexico or some such thing. I remember thinking that I could deal with a fetal pig better than I could a cat.
I did get pretty attached to my pig, though.
I wouldn't say I thought of him as a pet, but I did feel a little twinge today when we had to dispose of them. My prof said we could take them home and keep them in a jar for reference (which should give you some idea of what kind of a guy my prof is!), but I politely declined.
The first disection is hard, but it seems to get easier as the course progresses. Hopefully, you'll have a lab partner and you can share the duties, particularly initially as it will probably be a bit hard for everyone.
