I have a Venezuelan Curly Hair tarantula and she has not been eating recently. I have been counting the number of crickets i put into her cage and the same number are coming back out. It seems like it has been a couple months since she has wanted to eat, when previously she would eat as soon as they hit her floor. Honestly I can't remeber the last time she molted as it has been a little while and she is also getting older (I have had her for about 18 years but I got her from a friend so I don't know her exact age) Any suggestions as to what could help?
