I have four pets and really can't imagine having more. They do each need personal attention and direction (especially the dogs). The number 7 keeps popping into my head as becoming a hoarder. Obviously that would not include a litter of new puppies.
That doesn't sound like too many... some animals really don't take as much time as others. We have had rats, snakes, fish, hamsters, rabbits, hermit crabs... much easier that dogs!
I agree with Melissa's response. I think as long as a person can vet, feed, and love the animals they have, I don't see a problem with having multiple animals (I have 4 small dogs and 3 cats). Sometimes when my finances are tight, I think I might be wise to "adopt out" one of my babies - but I didn't adopt these animals to farm them out, and luckily, I have always been able to provide what they needed.
I do know that if you live in a city limits, there generally are limits to the number of animals you can have (in Sherman, I think it's 15 dogs!), but who is going to monitor and patrol this?
My goal in life is to be an animal hoarder (lol), but only to the extent that I can care for all of them appropriately!
I love my babies......
I dont think it's the number but more like the conditions in which they live and the health of the animal.
One pet past what you can realistically care for. For some that could be 5 - 10. Others would be higher. I know a situation where a woman had over 50 -- used her dining room as a litter box. Definitely a hoarder! But I also know of people that have land & have 20 - 30 pets but are in & outside animals -- & they care for them. Pretty much a situational type thing.
