Here's an interesting question - do you have a set limit on the number of pets you think is "too many"?
My wife and I got into a discussion about this yesterday as we brought home a new cat. We now have 8 cats, all adults, ranging in age from 4 years to 13 years.
All are housecats, get plenty of food, water, love and affection, and get yearly Vet care with all shots. We have 6 large litterboxes throughout the house that get cleaned twice a day. We also used to have 2 parakeets.
What about you guys? How many pets do you have, and do you think there is a set number that one shouldn't go beyond? I sort of feel like if you can provide for all their needs and keep them healthy, safe, and loved - then there really isn't a limit as long as you can afford them and keep them healthy.
